I've been on Poptropica since I was about 9. It's really fun, and some of the islands you visit on it are really educational. It teaches you problem solving, and things about history, plus you get to have fun and solve mysteries! Some of the islands can be frustrating, but once you solve the problem, you get a medal and 100 coins to use to buy clothes and other things for your character, but you do have the option of buying coins on a credit card though. There are places in each island where you get to play games and chat with other kids. They do have it so that its a safe chat. There is violence on some of the islands, like you might be "whacked" by a villain, but that's just part of the adventure. They constantly have a movie or something that they're encouraging, and you get to play some games based on it. I really love it, and so does my 8 year old sister.
