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.
Contra Dot Dance is not a non-profit and is run individually by a dancer based out of Washington. I'm not a lawyer or an accountant, but I'm pretty sure that means your donation is more of a gift and as a result is probably not tax-deductible. Odds are I have to report it on my taxes, too, but I guess I figure that out after putting the question off for a year or so.
All donations are made without a promise of goods or services rendered and in no way should be construed as a guarantee of availability in the future. Please don't come after me if I do something you don't like, I'm just a guy with a domain name, a server, and some spare time.
