It's hard to find a good signature for a Newbie !
maybe someone will prompt me where to look a signature or a good bounty? sites, groups?
Most signature campaigns apply for applicants with minimum requirements on newbie, but if you choose bounty I think many accept newbie to participate. Especially since the existence of the merit system that applies here, sig camp apply the rules are above jr. Member.
But you do not have to worry, because many bounty who can accept you. You just need to look for it in the bounty section.
