what type of campaign is this? what's it for/about?
You will see after applying. Then you can choose to enter or not. It is a review campaign
Are Newbies even allowed to have signatures anymore? I read recently that Lauda banned signatures for Jr. Members, which means Newbies would also be banned from that feature of account status.
Anyway, I can see why you posted this here, but you should put a proper announcement thread in the Services board so people can reply to it there and not have this thread clogging up the Beginners & Help board.
