Any parent whose child goes online will no doubt have worried about who they might meet and talk to in cyberspace. Think you know who you're talking to online? Think U Know is a site set up the Child Exploitation and Online Protection Centre in the UK, but its advice is relevant wherever you are.

First of all, I love the design of the site. It has impact without being over-dramatic, and it loads really quickly, especially the video on the opening page, which is well worth a look for any teenager who is new to online communities.

Parents should be aware that it's very frank and open about the potential dangers, so make sure you're around to offer support if they're disturbed by it. But perhaps better they be disturbed by the potential than fall into any traps.

Laid out in easily accessible chunks, covering all sorts of subjects like mobiles, podcasting, chatting and the like, the site teaches that the internet can be great fun, but to recognise the signs of grooming and abuse. And if they should come across trouble, there's an easy way to seek support and report an abuser to the UK police - just use the Report Abuse tab at the top. Here you'll also find sections aimed at parents and teachers. All in all a very good website.
