Some bounty campaign only requires is the newbie,.Most of them are rank with a Jr Member is allowed to join. Maybe you have some search with an newbie is required but you can't joined their signature campaign,. Only the rank up with a Jr Member and must be a higher rank is allowed to the signature campaign. But I think as a newbie required to a campaign is not a common to search with. You should need to level up with your rank to a Jr Member..so that you can join a lot of options for the participants.
