I put Sense of Community first, as I come here to get to talk to and get to know people like me. Otherkin are not that common, and from what I've heard, they are often bullied, hurt and teased in one way or another because of their belief.
Second would have to be Sense of Efficacy. I have gotten a lot of helpful tips here, and they have made me understand my Draconity better. Also, I have been given understanding of a few other things, like magic in the real world.
Then we have Anticipated Reciprocity. I want to try to help people understand things that I know about. I feel happy when I manage doing that.
Increased Recognition matters a bit as well, and I guess I have gotten this, as people welcome me back when I have been away for longer periods and so.
