Welcome to PokeCommunity! As Hiiro said, there's so many things here on PC (PokeCommunity) that it can't all be described easily. Of course, the main theme here is Pokemon, but there's a lot of other things as well, like music and culture. Where you hang around depends on your interests, but I'm sure you'll find something to do here. Well, once again, welcome, and have a great time at PC.
