My original username was EcoEclipse, which finds its origins in a roleplaying thread between a few friends on Gaia Online waaaaaaaaaaay back in, like, 2006 or something. I'd named my character "Eco," which in turn was swiped straight out of the Jak and Daxter games. The friend who was I-guess-DM'ing the thread affixed "Eclipse" as a surname; I don't actually know why. But it stuck, and since then all my accounts were EcoEclipse.
Until a few months ago.
Any of you who listen to the CommuniCast might remember me being on, what, episode three? Anyway, both Fappy and Daystar mispronounced it as "echo," which is something not even close to new. A few weeks later I was like, "y'know, my username kind of su~cks."
So I changed it to The_Echo, which I think not only sounds better, but looks aesthetically better and won't be mispronounced nearly as often. (On the other hand, I no longer have my name on the community signatures background...)
