personally, i disagree with the old one being organized. well, before i explain why let me just state it WAS a bit clean, but that's just it. the new forums aren't all that neat too, but i'm sure that'll improve within time.
anyways, the old forums isn't exactly up to date like atelier801 is. even when you post on a thread for the old ones, it doesn't bookmark you to where you left off, but instead it brings you right to the front page even if you've posted there before or went to the very last page. it doesn't provide yellow numbers or anything like that to determine whether you've posted on it before or not. this causes people to get lost. i understand there's a thing such as "last posts," but even i wouldn't want to go to my profile every time for that because our posts eventually disappear or just get lost if we're a user who posts often.
