Anyhow, welcome to the forums my little bucket of sunshine!
Here's a little lowdown of some of the (newish) rules:
-Don't double or triple post.
-Post at your own rate. Don't post for having like 100000 posts or a Red Name.
-No spamming (bad, baaad spammy >.<)
-Post at your own rate, don't post for fame or post counts o-o.
-Just have a plain good, jolly ol' time hur ^_^.
-Don't forget to read the Stickied Topic Threads in this section, they are your master of the forums (besides the mods and admins and the p4wn1ng p30pl3 :/)
I am one of teh smexy mods of this section and a staff member of the forums, so if you have any questions/comments/whatever, feel free to PM me ^_^.
Have a great time at these 'new and special' forums o.o
