LinkedIn is the world's largest free professional network. Students and career men and women are encouraged to join, create a profile, and build their network of professional contacts. LinkedIn can be used to make introductions, ask questions, find or post job openings, and establish a professional web presence.

What is LinkedIn and how do you use it?

Users build the network of professionals they know by importing their address books or entering individual email addresses. They can also join groups of their colleagues and classmates, where they can ask relevant questions, make comments, “like” discussions, and get answers.

LinkedIn contacts are listed by their name and the company or school they belong to. Users can send direct mail to their LinkedIn contacts, or they can send “inmails” to contacts of contacts through the LinkedIn platform without disclosing their email address. People can make introductions between two of their contacts who don't yet know each other.

In 2010 MySpace coined itself a “social entertainment destination,” marking the shift in focus from helping people connect with other people to helping them connect with their favorite music, videos, and celebrities.

Yet another study has been released that indicates the harmful effects of excessively watching television. This article was originally published on the Huffington Post by Amanda L. Chan. 

TV time could be putting a damper on your child's sleep time, according to a new study.

Researchers found an association between increased TV time and less sleep in kids.

"Overall, each additional hour per day of average lifetime TV viewing from infancy through mid-childhood was associated with seven fewer minutes per day of sleep over the same period," the researchers wrote in the Pediatrics study. The effects seemed to be especially pronounced in boys, compared with girls.

Catfishing, or faking the identity of another person online in order to create a relationship, is not that hard for a teenager to fall for. Predators are adept at exploiting a teen or tween’s tendency to take people at their word. Ten rules for using the Internet can help them avoid falling victim to catfishing:

Texting can be regarded positively or negatively in a household. Learn how to see the silver lining of texting and end up using it as a tool for digital parenting. This article was originally published on The Huffington Post by John Duffy.

My son George, my one and only child, is now an 18-year-old man. In a few short months, we will be dropping him off at college. He's busy focusing on his senior year in high school. That moment hugging his Mom and I goodbye on some quad a few months from now isn't remotely on his radar. For him, it's just some hazy, remote construct of a distant future.

But my wife Julie and I sense that hourglass emptying, that moment approaching in double time. We take turns being upbeat and distraught, our scripts ranging from how exciting this next chapter will be for him and how ready he is, to how quiet and dead this house will feel come September. We are both working overtime to be available to every moment with him, every swim meet, awards ceremony, late night talk, even silent breakfast. We drink him in, knowing soon, this iteration of our lives together ends.

Now, today is Saturday, and after sleeping in, I thought George and I might grab a sandwich, a frequent weekend tradition for us.

But today, he had plans with his buddies. He jumped in the shower, grabbed car keys and bounced. Of course, that's how it should be: a guy should spend Saturday having a good time with his buddies, not hanging around with Dad. That would have been my last choice at 18 too. Still, as he pulled away, I swear I could hear the opening notes of "Cat's in the Cradle" swelling gently in the background. Lump in my throat, I made alternate plans. I began to work, distractedly, in silence.

We already know that poor social media decisions can impact a teen or tween's future. Read on to learn about how a 7-day cleanse can help them refresh their online reputations. This article was originally published on McAfee Blog Central by Toni Birdsong.

Sorry, this post will not push the health benefits of a kale-flax smoothie (although they do rock). But, if your aspiring college student follows this 7-Day Digital Cleanse for a full week, he is bound to become more digitally fit. (Disclaimer: the side effects of the 7-Day Digital Cleanse could be life changing and dream saving).

By now we all know about the fallout that can happen when young people with big dreams fail to post properly on social media sites. We’ve seen Olympic athletes sent home for a tweet, a zillion people get fired, and college scholarships revoked because a tweet or photo made it to the desk of a college decision maker. 

In 2013, Kaplan Test Prep surveyed nearly 400 college admissions officers and found that 30% said they found something online that negatively impacted the applicant’s chances of getting admitted. On the flip side, when canvassing students in a separate study, Kaplan found that 50% of students admitted they would “not be concerned” about an admissions officer researching them online while 27% said they were “not too concerned,” and 14% said they were “very concerned.”

Offenses cited in the admissions study included essay plagiarism, vulgarities in blogs, alcohol consumption in photos and “illegal activities.”

Tumblr is a free microblogging site where users quickly and easily post short snippets of text, quotes, photos, videos, links, music, or whatever else interests them in a rapid-fire fashion.

You've heard of helicopter parenting. But how about those parents who don't only hover -- they're out there in front of their kids clearing every obstacle? I call them "snow blower" or "lawnmower" parents, and although their efforts to protect their kids come from a good place, they're not allowing them to develop the skills they need to recover from setbacks -- to be resilient, in other words.

I'm part of a growing movement of what I call "Resilience Parents." We're doing our best to raise kids who can clear most of their own obstacles -- and get back up when they run full speed into one they didn't see.

Here's an article coming from our friends Kelly Karius and Sue Scheff! Kelly Karius elaborates on a previous article written by Sue Scheff and shares insight about where bullying labels develop and how to change our way of thinking regarding the issue.

I was drawn to Sue Scheff’s Huffington Post article “Grownup Bullying and Monster Moms”Immediately. She had me from Hello. “I know bullying and cyberbullying is a topic that many people are becoming immune to.”

We are. And I believe I know why. Two reasons:

1. We are currently labeling everything bullying.

2. Adults don’t acknowledge their behavior. So why should children?

See what measures that middle school administrators are taking to exterminate a dangerous new trend that is circulating among students. This article was originally published on the Huffington Post and is written by Rebecca Klein.

Students at one Connecticut middle school aren't using pencils solely for taking notes. Some are rubbing their arms with pencil erasers until their skin is mutilated.

School administrators at Bethel Middle School recently sent a letter home to parents and guardians asking they talk to their children about a dangerous game called the "Eraser Challenge."

The game, the letter explains, involves kids “'erasing’ their skin while saying the alphabet and coming up with a word for each letter. Once they get to the letter Z, they stop and then compare the injury to their [friends'],” according to the Bethel Patch.

No one ever said that raising kids was easy.  Raising kids in the digital age presents a unique set of concerns and challenges that your parents never had to worry about. However, what you don't hear often is how technology can actually help keep your kids safe and sound. The advent of smartphones, GPS, and widespread Internet access need not only be a source of fear for concerned parents. These technologies can be used for parental monitoring and peace of mind. There are many examples that can highlight this, but perhaps one of the most exciting examples of this concept is the smart watch.

Smart watches are the latest trend in mobile and wearable technology. New smart watches are in development from some of the biggest names in the industry. This is an exciting and cutting edge trend, but what value does it have for parents? Smart watches with built in GPS and cellular functionality present a great opportunity for parental monitoring.

As the editor of HuffPost Teen, I spend a good part of my day talking to Snapchat-sending, Facebook-hating, selfie-taking, iPhone-obsessed teens that many adults love to judge. I also talk to their parents.

This week, I received a fairly typical email from the concerned mom of one of our bloggers asking questions like: Is having an Internet profile safe? How many people will see it? Will strangers try to communicate with my kid? What about online predators?

Cyberbullying and sexting aren't the only things that parents need to worry about when a child begins to use Facebook, Instagram or other social media sites. There can be monetary consequences if appropriate Digital Parenting techniques are not put to use.

Take for instance the case of Patrick Snay, he won an age discrimination suit against an employer, or so he thought. His daughter posted an announcement to Facebook about the victory before the deal was completed. This violated the terms of the settlement and a court agreement. It cost Mr. Snay the settlement of $80,000 and caused emotional distress for his entire family.

We just released a new infographic yesterday about the dangers of online identity theft, especially in children.

• Did you know that 7% of all US households reported some type of identity fraud in 2013?

• What about that $21 billion in financial loss was attributed to identity theft in 2013?

• Or even that your children are being targeted for identity theft 35 times more often than you are?

View the infographic for more information and the 6 easy steps you can take to protect your family and loved ones from identity thieves.  

In today’s world, having a cell phone is not just a convenience for adults.  Parents of pre-teen and teenage children should consider buying cell phones for their kids. Far from being something to make the kids happy, those cell phones can also be a powerful tool for effective parenting.  Consider these five examples of how a cell phone for your child will provide protection and also help you keep up with what your kid is doing.

Getting a Ride Home

While you don’t like to think about it, kids can find themselves in all sorts of situations, some of them not of their own doing.  Perhaps your child was out with friends when some activities got underway that he or she did not want to be involved with.  The trouble is that your child needs a ride home.  If you have provided the child with a cell phone, all that it will take is a quick call to you or another trusted adult, and someone will be on the way to retrieve your child in no time.
