Hey Noah, welcome to PC! I haven't played B/W2 in a while but I agree that it was a really cool game. What did you like the most about B/W2, if I may ask? I thought the storyline was great. It definitely felt like a huge step up from B/W for me.
Anyway, make sure to have a look around the forums and see what sections you might be interested in on here! Others have already beat me to it but the Fifth Gen Board might be a good place to start. If you want to talk about B/W2 then you're always welcome to send me a VM, otherwise have fun around the forums. :D
