Are you talking about bounty campaigns or signature campaigns? I know most bounty campaigns doesn’t require a specific rank before you can participate in them, if you are at least member rank, then you should be able to participate in signature campaigns, but as we can see currently there is no signature campaign that’s accepting member rank, campaigns available are accepting full members upward, and recently you will find it difficult seeing a newly launched campaign accepting full members, most of the campaigns available now are accepting senior members upward.

You were inactive for so long, so you should definitely expect changes in the forum, I don’t know why you left forum for so long, but if you want to participate in signature campaign, then you should keep on making impact on the forum, and am sure it’s going to be easy for you to attain senior member rank and above, but I will say you came back because of signature campaign.
