My username is a combination of random letters and numbers I pulled from license plates when I was working at a salvage yard. Retta has been an alias of mine for a long time, usually with other things appended to it.
Avatar is a picture of Jack Bartlett from Ace Combat V, old PlayStation 2 game I was a quite a fan of at one time. It could use a resolution bump as the current image is 192x192, back from when forums needed a tiny image 18+ years ago.
