Is there any bounty for full members ?
One that has open spots ? I joined old ones in the past but now all I see is campaigns restricted to Sr members and above.
It's not actually intentionally limited to Full Members, but for now there are just not many campaigns that open spots for Full Members so it seems like users with that rank don't have a chance to be in a better campaign. Also, for now there aren't many signature campaigns in the bounty section so users with a rank like you still have to fight to increase their rank so they can have a chance to be in a better campaign and not just in the bounty section.
So what best he can do for now is to maintain his activity in forum and try to rank as Senior. Since if he goes inactive again and remain in that status then provably that same as what happen he might struggle to find campaigns for his rank.
Also there's merit requirement if there's open campaign so he need to earn good numbers of merit to qualify and get selected by the manager.
So for sure that he learn from lots of inputs provided here and patience is really important since for sure there are new campaigns in future that will accept Full member ranks.
