livelongnmarry is a community raising money to fight the evil amendment on the ballot in California this fall that, if passed, will undo the state Supreme Court's decision in favor of marriage equality. They are doing this by having an auction. Community members auction off goods or services and the buyer donates the money directly to an organization working for marriage equality.
I would want to make a donation anyway, and it's fun to potentially get something in return! Most of the offerings are fanfic (that's what I offered) but there's also some jewelry, clothes, a variety of services from beta reading to tarot reading to help in choosing a therapist, and some care packages, too. There are many, many offers, but a tag index lets you find all that are in a particular fandom or of a particular type of offer.
Go check it out!
