Chances are as a newbie you can not participate in signature bounty campaigns. This is because there is no space for signature link since you have not been upgraded. In most cases for you to be accepted, you must be a Jr member. You to be active and must have done up to 30 activities to be ranked so. As a newbie your best bet is to participate in other bounties like facebook and twitter campaigns.
My friend says, if you are still a newbie do not expect to follow any bounty program or campaign first, because that will happen later is just spamming in this forum, because still lack of knowledge about crypto world and about this forum, so we should read more and learn first.
