Welcome to PC, Treeckowned!
There's a good deal that you can say in your welcome! After all, it's a thread just for you! We always like to know why new members join and what their interests are. That way, we can get to know you a bit better! This is a PokeCommunity after all =P
Anyway, I'm sure you will enjoy yourself here. PC has a whole lot to do and some awesome people to meet. Once you get posting, you'll be having fun in no time!
Please do read the rules/FAQ, and feel free to PM/VM me if you're ever in need of assistance.
I'll see you around!
