Just so you know, THIS IS WHERE THE COOL KIDS HANG OUT. AND HAVE PARTIES.
In all seriousness, though, welcome to PC! And you'll definitely have tons of fun! If you're pumped omg about B/W2 (and don't mind spoilers), I would direct you to our Black 2 and White 2 section, located under Current Generation Pokemon Gaming (which also houses B/W and Fourth Gen games). Or if you just want to talk about Pokemon in general, you can check out Pokemon...general, lol, located under Alternative Pokemon Discussions. If you're into the anime, it's also located here.
If you have interests other than Pokemon, though, I would recommend just about anything under Off-Topic Discussions. Especially Other Clubs, it's always fun in there!
Make sure to read the rules and contact a mod/admin if you have any problems!
