tl;dr version: I want to set up a contest, but I don't know how. Help/advice/suggestions?
You and I could be a team on this. I just announced my contest a few weeks ago, called "The Reruns Contest". The idea is you can use any of the limitations from one of the previous contests (there's a list on the page I linked to), and that will include the in-a-tin contest. Geekmail me if you're interested and we could run this thing. I looked up all about how to run a contest, so if you want to know more, we can put our heads together.
I'm putting 75 GG into it, do you have any GG to contribute?
