It really is hard to find good bounty campaigns for newbies. Most of the bounty campaigns only allows Jr. Member and up to join their bounty. My advice is that you keep posting and stay active on the forum to be able to rank up and join most of the bounty campaigns you want to participate in. After all the higher your rank is the greater rewards you will earn from the bounty campaigns you participate in. But if you really want to join a bounty campaign with your current rank be patient on checking the campaigns that fit you in the bounty section.
