Try not to post anything too personal/identifying, like your full name or address. First name is fine, a lot of people know the first names of most staff members and cool users and such. And try not to be too offensive in your posts. A bit of vulgarity is fine here and there, but incessant use of potty language could land you in trouble. I think. I didn't read the rules
Aside from that stuff... Just be cool and enjoy your stay. PC is probably the forum I've had the most fun with (except first Nintendo forums. So many memories. RIP Ninty forums) so I'm sure you'll find a home here.
What are some of your interests/hobbies outside of Pokemon? We've got quite a bit of non-Pokemon related boards. I frequent the Treehouse board most often, which is just for random shit, but there's also a super cool Art & Design board I like going to view pretty stuff by our members.
