Gather with payment proof!
Invitation Landing Page | Gather
This was pretty easy.
I had to get five unique people to simply sign up, and got a $20 Borders Gift Card. No one ever has to do anything but be a unique sign up. However, they do offer points for additional referrals, article writing, group building, comments, and the like. I posted a few articles and already have 198 points toward more gift cards (and if you earn enough points, they'll give you CASH!)
