Now through October 16, the OTW is holding a membership drive to raise the funds needed for us to keep owning our own damned servers, plus supporting the Fanlore wiki, Open Doors archive and zine preservation efforts, legal advocacy services, the Transformative Works and Cultures journal and future projects down the line. OTW membership costs just $10 (USD) and also gives you a vote in the upcoming OTW Board of Directors election. If you've got more than that, there are some cool premium goodies available too.
What's extra cool is that right now there are not just one, but TWO matching grants available (one general grant, and a grant specifically honoring Sandy Herrold) which means that whatever you're able to contribute will be doubled! Details here. If you've been meaning to join or renew, this is a great time to do it.
AO3 [archive of our own] is part of Transformative Works, as well.
