I had the user name Nymphadora_Tonks for years... From the point I joined Gaia (March 2004) until about two years ago. The only reason I changed because some girl made her user name way to close to mine, didn't have the little _ in it, and every time I tried to log in, it kept saying that my password wasn't right. It was a major glitch that was happening a lot at that point in time. So I just finally chose to change my user name. I use to have an account U.S. Air Force Airman which was banned back in 2010 I think Oo;;; can't remember, was a while ago, so I though to fix the issue, I would combine the new names into one ( that way my friends from Airman would know it was me)
My user names always had a lot of meaning to me as a person. Nymphadora Tonks was my favorite character from Harry Potter, so that's why I've always gone with that name for almost EVERYTHING I do. My U.S. Air Force Airman account about right around the time I signed up for the Air Force, so it had a ton of meaning to me as well. Served for 5 years and deployed twice. Was very proud to be an Airman. So now, my user name has double the special meaning to it.
Mine really isn't overly creative or really fits into any category I think. The most places I frequent are in here, the Gaia Exchange, and the Art Forums. So I guess that could be the reason why, because I have kind of a broad forum interest on here.
(Sorry if there are a lot of typing errors, I'm on my phone, and my auto correct and fingers don't always agree with what I'm trying to say sweatdrop )
