Contra Dot Dance
I bought http://www.contra.dance because I thought it would be a clever and useful way for dance callers, bands, and organizers to get the word out about what they're working on. It's a labor of love, and I personally pay for it all out of pocket.
I don't personally mind the cost, and I'm not in a position where I'll have to shut things down if nobody helps out, but if you like the concept and you want to help keep the lights on, I'd really appreciate it.
