Hey there. Welcome to SPPf.
Read the rules, stickies, and the Newbie FAQ to help you get you started with posting. Follow the the mods, smods, admins, and all above. Update yourself with the SPPf Current Events in the Serebii.net Announcements section, and also read all the special announcements by Joe (Serebii). Try not to spam on a daily basis or curse often, that will help improve our forum. Don't reply to threads that nobody has posted in for more than 30 days (a month), and do't bash/flame/berate any of the members. Ignore the n00bs, as they do nothing but make you miserable while you're here. Anyway, if ever you need help, or need a friend, PM (Private Message) the forum elders, or get adopted in the Adopt-a-Newbie Agency.
But most of all, try to have fun and enjoy your stay.
