Eminently.
Been using this name in many forms for over 20 years.
It is my Tao. 
I just had mine changed this past week and I’m happy with my decision. I used to go by r4nd0mnumb3rs which was cumbersome to type and I never really liked it since I just kind of made it up on the spot. I go by ‘Acid refluX’ on multiplayer games since it sounds like a l33t hax0r name but is actually just an irritating disorder that causes recurring heartburn.
No, the last G is cut off. I didn’t get any warning that my chosen name was too long when I picked it, otherwise I would have taken out the spaces.
Nope. I’ve outgrown mine: I no longer play lacrosse for WMU. I’ve been racking my brain for a new one for weeks now, but can’t think of anything.
Huh… I thought it was on obscure joke about formin homology proteins. Oh, well, I suppose you could work up said joke for future reference. It’d be just the sort of thing people like around here.
Please leave it. I love Team of Scientists. It makes me think of The Venture Brothers and the shows from which it draws its inspiration. So it always makes me happy.
My name I think I’d like to change. I’m tired of Bambi and I think I would prefer Velveeta du Soir or Coco Brown or something more drag queeny.
I like mine now. I was LaurAnge for many years, and although I had grown up with it (I used it, or variants, from the age of 13-23) it didn’t say anything meaningful about me anymore.
My current name says: female, mellifluous; and to those in the know it shows my interest in ancient myth.
I’m not particularly thrilled with mine, but I’ve been Astroboy14 so long and for so many different things online that it would feel wrong somehow to change it now… though if I did, I think I’d go for something like Some Random Jerkwad.
I’ve started working on it, but I guess I don’t know enough about molecular biology to formulate a good joke about it, and if I did, hardly anybody would get it. Maybe I can work something out that has to do with actin.
I like my name. I wanted to use my handle from previous boards (Iblis) but it was taken so I had to use something else. And I’d just read the Illuminatus Trilogy and really liked the idea of being in the Illuminati so there you go. I tried to use it as my handle on another couple of boards that I’ve joined in the last six months but Illuminatus was gone and Illuminatiprimus was too long so I’m something completely different there. Talk about multiple personalities!
Helen’s Eidolon, I really like your user name, please keep it!
Oh, and I’m glad 1010011010 posted here because that was one name I immediately thought of when I saw this thread. 
Same here! I love the picture of four or five people in white coats staring at a computer screen and debating the finer points of shoe etiquette and scalar weapons.
Bambi, please keep your name too!
I’m happy with mine. Gender allusion, check. Personality descriptor, check. Character from movie who created wicked awesome car, check. Plus, I get to use that great quotation from the movie as my sig line.
I don’t like mine. It’s more of a pnemonic login than a name that I picked. Then I started posting, and I feel stuck with it. It doesn’t mean anything. Didn’t everybody used to (how about that grammar?) have usernames with numbers, in general?
I’ve been thinking of changing it. I do, then this post will make less sense but it will be obvious because it won’t have numbers anymore.
Mine’s an anagram of my name. It’ll do
HA! Figured out your name! It’s Black Nerves, isn’t it? You’re a William Gibson character! 
I like mine. It doesn’t really mean anything to anyone, it’s just a character name that my husband made up, and it cracked me up at the time. I still laugh at it sometimes. It sounds like the name of a damsel in some silly medieval parody.
Now and then, though, people think I’m really presenting myself as a frail individual…how emo is that? I have to tell them it’s just a funny name.
Yeah, but I read once how your username came about, and I think it’s still perfect for you. I mean, it has a little of your history, your brithday, and it has a mysterious quality to it: “Olives march forth!” Sounds like you’re ready to take on the world!
I like mine because as long as I use it, I’ll remember one of the funnest moments I’ve ever had at work. Besides, it’s sort of trans-generational. I can be either young and hip or old and lame (and at my age, “lame” takes on lots of new meanings). I think I’ll keep it.
My name was a nickname my dad called me when I was little. I like it, but sometimes think of changing it because it’s such a part of my history that I feel exposed, as if I were using my real name. But I am boring and have no imagination and so I can’t think of another name that would suit me.
Fetus - you got me in one, Black Nerves is my name.
(dammit - black nerves is so much better than KC Bravelens! Why didn’t I think of that?)
I’ve always had the hankering for the user name "Giant testicular,tree juggling fuckwit,monstrosity the third,Victoria Cross and bar"but there was simply just too much typing involved.
