50 posts saying anything...
Just no spamming. Like a certain member has been doing lately... that might just get you banned instead. Go around, show genuine interest, don't just post 50 one-two word posts in every thread, no double- or triple- (or more) posting, etc. If you can help, do that. Frequent the Off Topic section, that's an easy way to up your post count, particularly the 'guess who's next' game, especially if Rain or Nick are on and active in there lol.
Just read and stick to the forum rules and you should be good.
