You are not being specific, OP. Do you mean a bounty campaign or a signature campaign, because I checked bounty campaigns accept all ranks and up to newbies are accepted into bounty campaigns, but signature campaigns, as we all know accept from full members above, although some signature campaign managers accept member rank and there has not been anywhere it was stated as you have said. I checked your profile, and I would say that you should take time to work on your account and improve yourself, as currently, you really need to be very active before thinking of putting in an application for a campaign spot.
