As for now, I think you should increase your rank and gain some trust yo make sure that you are eligibel to be part of the campaigns. In order to gain some rank and trust you should really pay attention on what you said and how you act to the forum as well. And btw nowadays there is new feature called merit which you need to gain higher rank too. I believe there is many information here, you should try to read and it will slowly gain your reputation, rank, merit and trust
