Hi there! Welcome to the forum!
What are you primarily interested in? Telling us more about yourself will help us point you in the right direction in terms of threads that may interest you. We have many different sections here at PC. We have sections for the Pokemon games, anime, TCG, battles and trades, etc. We also have a variety of non-Pokemon sections too, for discussing things such as other Video Game series, TV/Films, world discussions, etc. Rom Hacking is pretty big here, and I am not sure if you are interested in it, but we have a large section for that too if you are.
Hope to see you around :)
