How do you guys pick a signature bounty campaign? There are so many of them listed and with such different requirements, I'm lost. Now that I'm a jn member I'd like to participate but I don't know where to start!
You don't know where to start or you don't know how to start.You are a Jr.Member and so you are eligible for signature campaigns too. You can find many bounty campaigns and signature campaigns under Economy> Services .
You can join any open campaign that is eligible for Jr.Members that suits you and be a part of it. If you don't know which one to join then you can join the one which you think can be accomplished by you.
Whatever you do just try to make constructive posts as they are the ones that matter the most at the end.
