It seems like most people change their username until they're happy with it or their interests change. Add that to the fact that TCoD has had multiple forum moves and has been around for who knows how long, it seems like a thread dedicated to listing your old usernames would be a great nostalgia fest and have a bunch of wonderful 'Wait, you were sakuraloverkitty7636?' moments.
As for myself, I registered at the IF forums as Zyronixx and quickly changed it to Zironixx after I discover that Zyronixx had results on Google while the alternate didn't. After the forum move to the first VB forums, I used the username Wolfie, because I was such a dork back then. Sometime later, I decided the ridiculously long Oddly Hydraulic, Kay¿ was a better option. I finally and thankfully settled with the much shorter Spoon after having a sudden spark of inspiration after picking up a spoon to eat some instant ramen. I forgot my password to the Spoon account and made an alternate account called Spoon-Fork. I managed to remember my old password, which got me into the position of having two accounts. >: Then TCoD imploded. The second and current VB forums were created and I registered as Spoon. (I've had a few other usernames, but I don't really think they're noteworthy.)
