If you're between 11 and 16, you probably know a lot about using the internet.

Think U Know.co.uk - created a space for you to share what we think is good, look at what's not, share experiences of things that have gone wrong and show you ways you can get yourself out of bad situations.

You'll see they've split different things you can do into sections. You can also watch films, play games and report if you think someone online is being weird sexually with you.
