Another option is Smalldog Electronics, which will match donations to Doctors Without Borders. I'm not sure how a company can afford to make such an open offer, but assuming they're serious, it's lovely of them. Doctors Without Borders does note on their website now that they've as much funds as they can effectively utilize for tsunami relief; money sent to them will go into their general emergency fund -- which is of course what they initially drew on for sending immediate help to South Asia. They spend a remarkably high percentage of their funds on direct support (see image right, which reminds me that I need to draft something similar for the SLF annual report); this is part of why I like them.
And Sulekha, an online magazine, appears to also offer a matching fund, tax-deductible in the United States, in partnership with AID (Association for India's Development). I'm hesitant to recommend them without learning more and making sure they're okay -- Sulekha published me, long ago, but I don't know anything about their possible politics, reliability, etc., and ditto for AID. If anyone reading this can vouch for them, that'd be appreciated. I'm also not sure I understand how high the fund will go -- if I understand their site right, you can choose to either just donate (and be matched), or have your donation go into the matching pool -- which means half as much money initially, but potentially more encouragement to others to donate? Huh. A bit confusing. I'm not sure how that's any better than just donating directly; it seems like they're not really matching it themselves, beyond perhaps the initial amount?
