ive had the same tag (SADER) for about 10 years now. I just picked letters I liked doing in an order that worked. I changed it a few times but eventually just came back to the old one.
since I'm getting into ooglery i recently started trying to play around with monikers, and made this lil doodle girl that I think is cool, but I'm not sure if I'll keep it. moniker stuff is like a whole different style to learn.
