Don't know that it counts but I do what I can to assist LGBT people around me. Sometimes it's just offering them a list of resources and other times I help them pay for things they need (this is predominantly for trans people). I'm trying to be a little more proactive with trans people since they need the most help, and I'm paying for two trans friends to move out here and live with me. Gonna be taking care of them until they're able to stand on their own, so to speak. And there are an additional three trans people I am working with to assist them on vocal training, among other things.
Haven't done anything with in a bigger organization, though.
