A website to help children learn about how to use the internet safely has been set up by the police.
They've built a site that looks a bit like a Cybercafe, and want kids to log on and then work their way through it with a parent or another adult.
Police say that around four in 10 children aged between eight and 11 are using the internet regularly.
The police say they don't want to stop kids from going online and having fun, but they do want them to be safe.
The police added that just under one in 10 11-year-olds has access to a webcam, which is something else children need to know how to use safely.
The site works as a series of games.
You help friends of a character called Griff to do their homework in the Cybercafe, and hopefully learn more about staying safe at the same time.
