I'm a terrible person because I'll rarely donate to overseas charities. I agree what's happening in Japan is terrible, but with my limited income (more limited now that I have Bizmark), I'd rather donate to this close to my heart and closer to home.
That said, I will do things to make other people donate to help out Japan. allthingsholy is doing a Write for Relief: A Fandom Charity Fundraiser to help raise funds. There are a list of charities over at help_japan that people can donate to. I'm covering three prompts (Supernatural, Leverage and Dark Angel) or 1000 words or more.
Yes, I know I have a bazillion other things to write, but I've got ideas for each fic, and they'll help me practice writing the characters. It takes me about an hour to write 1,000 words when I'm on a role, so it should be good.
Anyone interested in beta-ing any of these, just let me know.
