Welcome to PC, Umbreon! Fantastic to meet you.
Glad to hear you're excited to be part of the forum. People that are anxious to participate get the most out of this place since you have so, so much to do. Go on and get involved - plenty of boards all around for all sorts of people, whether you want to discuss X and Y, trade/battle, join some clubs, try ROM hacking, or what have you.
If you need suggestions on where to check out feel free to let us know! We're all happy to provide tips for the confused new member as we were all there at one point, haha. My personal suggestions for places to help you get settled in are Pokemon Clubs, Fan Clubs & Groups, and Chit Chat Cafe.. all three are fantastic sections where you can kick back and relax.
Of course there's more where that came from, too! Enjoy your time and see you. :D
