In case you are still confused, or just didn't read the rules, a thread that is asking questions like what's your favorite anime/game/movie/color. That's a favorite thread. If you have a question of if your thread is apropriate or not, ask somebody. Probably someone who has been here a little while. Or a mod. Admin's are usually busy when they're on. I hope this helps.
And as to the previous question by Baal, you do not need to get double, but you will need to get to 500 actual posts. So if say you had 250 posts and you bought 500, your post count would say 750 posts. But untill you got another 250 real posts, you will not get elite member status.
