my official explanation is that it must be a permissions glitch because I really had no idea what I was doing when I set up the forum LOL. I don't mind at all if people change their username so feel free to do it if you can, and if you can't then just send me a PM and I'll do it for you (which is what I've done for other people who've made that request in the past).
I'd just ask that if folks do it, unless they did it to hide from someone stalking them (yes, that is a reason one person did it) that they post in the Introductions area that they just changed their name so anyone conversing with them knows
I'll see if I can fix that glitch as well
