I am responsible for a few folks: Halsted, Aynne, and Kevin were either told by me in person about SF0 or found some post I made about it. And I think Derek joined because of a post I made on SF Metroblogging.

I've also recruited Nicole, Ernie and Eris, though they haven't met the two-task requirement this task requires. And I could try to claim my roommate Courtney, but I think another player told her about the game long before I was tipped off to it myself.
