hello there and welcome to the forums! there are lots of cat lovers in the board, though sadly i'm not one of them since i'm much more of a dog lover rather than a cat lover, but i do admire cats because i love how cute they can be if you do take pictures of them and all, and saying meow is just so kawaii, isn't it? x3
if you basically love pokemon, then this is the perfect place to be. there are lots of boards around and pokecommunity is certainly huge, i'm sure that the pokemon gaming discussions will interest you the most than the other boards around, but who knows, you might get interested in something else, there are definitely lots of things to do here and things to contribute, so take your time to explore and at the same time you will be able to meet lots of friends too, if you ever get confused, the staff are there to give you a hand so don't hesitate to contact them! o/
if you've been in a forum before, i'm certain that the first thing that a member should do is to read the rules right? since it's the key to just be fine here and not to get banned or get punished or something, and no one really wants that to happen. so make sure to follow the rules all the time, but if you still haven't then it's not yet late for you to read it since your just starting out! ^___^
have a wonderful time here in pokecommunity and please do enjoy your stay, loves~
