Like what i've done in this forum for a long time.

If you're really interested to participate in signature campaigns you need to spend time looking for a campaign that are accepting jr. members, because there's only few campaign that are accepting newbies and jr. members, that's why it would be nice if you have to level up first your rank at least to member rank.
