I don't know these folks, but popelizbet is running an auction at save_dave to help save her friend's house. They are trying to raise $7k to avoid foreclosure. This isn't just somebody's house, though, but somebody who has let lots of people use his property for parties and camping and clearly given to a lot of people. And when people are so generous I feel like it is the least I can do to give them something back, even if their generosity wasn't directed at me.
I went over there and offered art for auction. If anybody else can give stuff, go do it! I think internet stuff that doesn't cost you anything but your time is totally acceptable. Otherwise, I will let folks know when the auction starts in case anyone wants to bid.
