HERE'S A RANDOM POST FOR YOU ALL:
When I first signed up here, I couldn't really think of a good username for myself. I don't think "rainbowmancer" really fits me anymore. I used to have this like "super saturated and colourful coolness!!" persona for myself online that I just don't really think fits. I tried kind of playing into it but eh, now I know it's just not really my thing at all anymore.
Also, I always change my mind on this sort of thing immediately later. The only username I have been able to use consistently is NEOGEIST. It isn't really tied to a specific thing I like in the moment, it's just like, "this is my name combined with a combined with a cool-ass word!"
When it's possible I would like to change it by giving NG a few smackaroos. I can't do that right now though.
