This discussion-level article is a handy place for people to share info about their recent donations, especially donations to unusually efficient or effective charities. Feel free to post your one-time donations, your recurring donations, and/or any interesting changes in your donation habits. Gratitude and appreciation for other people's donations is also very welcome.
Did you donate to a registered charity? Does your government exempt you from paying income tax on charitable donation?
In France the notion of "charity" is tied to a restrictive list of associations so recognized by the state; a donation is tax-deductible only if to one of these organizations. I've donated e.g. to Unicef on a tax-deductible basis.
That will not apply to my donations to SIAI. (On the other hand, I can't (yet) bring myself to think of SIAI as a charity. I donate mainly to encourage the continued existence of LessWrong.com - if the promotion of rationality is "spun off" to a daughter organization as the SIAI strategic plan suggests that's what I will continue donating to in the short term.)
