the best advice i can give you, is to not log in to the forums.
if you don't want to use the site, clear your profile, and just not come online
as far as i'm aware, V bulletin don't delete acounts, maybe if you've not been on a while... i don't know.
but yeah..... that's my advice. just don't log in to the boards
and btw, it's my first post from you i've seen on here, and it's ashame to see you leave.
take care in what ever you do in the future
