Thanks Hollow (and everyone else!). We found out the early part of this right around when Greenlight was announced, but even then we had very few details and were nervous about announcing anything. Even now we're still working out the details, but it's progressing along, plus it was kinda discovered , so we figured we'd go ahead and make it official. Hurrah!
To answer your "how" question, I was getting ready to email Edmund and start putting together some other campaigns when out of the blue we were contacted. The ultimate "how" was through their web submissions, though it had been 7 months since the first submission, followed by roughly monthly submissions. Apparently sheer persistence was effective, though I think Greenlight has the potential to really do wonders for the process.
For FigHunter, while I can't claim to be directly responsible for it, I work at Kongregate for my day job, and we've sponsored some (or all?) of the Mardek games - doing our best to keep him going too.
