Some people have refered to a supposed rule that you only get one name change.
That is not true, there is no such limit. The actual rule is that Tubadiva doesn’t want people changing their names back and forth on a whim. Your first name change is pretty much given automatically. But you can change your name more than once, as long as you convince her you’ve got a good reason. Don’t be a jerk about it in other words.
I see you’ve changed it now. I think it’s a good idea, because I must admit that I always confused erie774 and elfkin477. The fact that (I think) you’re both rather young Republicans didn’t help any. Now maybe you’ll start developing a distinct identity in my mind. 
What’s the signification of Slypork, by the way?
I like mine. It’s who I am all over the internet.
Plus, what’s not to like about a Welsh goddess?
I plan to change my username, but I’m going to wait until after the Dopefest to minimize confusion. My major gripes with it are:
It looks best to me in all-lowercase, but a lot of people habitually capitalize it, and if I correct them they can get rather offended.
I can’t say I blame them on either count.
It says nothing about me, except maybe that I think there’s always room for growth and self-improvement, but that’s a cop-out since I didn’t have that in mind when I chose it.
It’s an inside joke, and I haven’t talked to most of the people who are in on it for about three years. The others have probably forgotten.
I kinda stole it from a basketball teammate in high school. Sort of.
It’s completely impossible to search for.
Not that coincidental–when I finally tried reading your name backwards I just figured it was a reference to your location.
I had a Wile E Coyote plush doll when I was a kid, and I lurved that thing to death. My mom’s coworker gave it to me–he didn’t know anything about me, and I didn’t necessarily even like Wile E coyote that much, but for some reason that toy was the key to my heart, and presumably to my parents’ thusly.
**Rhiannon **was one of the usernames I tried to get. No dice.
I would prefer the name I use everywhere else, but someone who doesn’t post a lot uses a very similar name and I didn’t want to cause confusion. (I just happened to see a post by that user the day I signed up) My previous username, Harimad-sol, also suited me fine, but I was confused for a couple other posters while using it. So far I have only been mistaken for someone else once with this name.
I like the name, though, and wouldn’t change it again if I had the chance.
I like mine just fine. Easy to type, relatively unduplicated. It’s not “me”, in that I’m not much of a traveler, but I choose it because it’s the title of a song (and album) by The Guess Who, a band that I still derive great enjoyment from listening to. It gives a ballpark hint to my age (if you know it refers to the song), and probably gives no clue as to my gender, both of which are fine with me.
I am not. There have been unanticipated annoyances. Yeah, I know: :smack:
It’s one of my fan forum usernames, and I’ve already had a fellow member of an obscure fandom Google it looking for stories. There’s no fic posted under this name-- they found SDMB posts instead. I try to maintain a higher level of anonymity on fan boards. Consequently, while I love it as a fanfic pseudonym, I need to find a new Dope handle soon.
I deliberately chose a silly name from a children’s book to discourage myself from wading into arguments with lefties in GD and the Pit, which would raise my blood pressure and exhaust my time.
Once in a while, however, I can’t resist wading into those arguments anyway, and I always feel a little incongruous doing it as Freddy the Pig. I feel like Tinky Winky telling Baby Bop he’s a brain-dead douche.
I dunno. I’m not completely attached to it. I’ve been trying to think of something good for my XBox Live Gamertag, so, if I ever come up with something, maybe I’ll make that my SDMB tag too. The problem is, EVERY iteration of EVERY numberless name EVER is taken on XBL. I tried putting in Hans Sprungfeld, a relatively obscure throwaway joke from a single Simpsons episode, and, well, you get it. (My current tag on XBL is A Soviet Spy, in case anyone is curious/wants to friend me)
Anyway, I stole this name from some chat room. I got a chuckle out of the notion that a team of scientists is deciding by committee what to say in a chat.
So, Chefguy, if you’re not a chef, what’s with the handle?
Oh, I like mine. Distinctive, easy to search for. Granted the real one was a pretty nasty piece of work :p. But like I’ve related before, my attraction to the name itself pre-dates any real interest in history.
It was either that or Prester John, which would have been fine as well.
Tonight I briefly considered changing my handle to Scotsman having sex with bicycle, but I think I’ll leave it alone.
Heh. I thought you were a gay guy. Who looked like a wookie. Who drank a lot…
Just got mine changed, actually. A bit more subtle than my previous one.
Considering I just joined and picked my out… 
I like it…
Sort of fits my mid life crisis, mode, 'cept I am only 29. Totally dreading 30.
Sometimes when I’m feeling neglected and disrespected by the intelligentsia and dismissed as hoi polloi, I think about changing my username to something more literary, classical or obscure. Since it would be fake to me and wouldn’t be organically inspired, I rather remain who I am.
Besides, I really liked that band at the time I joined so, at least that name means something to me.
Ditto. I should’ve thought of Pitocyn sooner, but that’s my vanity plate, so I must be content.
It’s too much bother to have the mods alter me.
Your username gives me an earworm each time I see it. Various songs, though “100 years” is the most common one.
I’d yell at you, but I’d rather have a Five for Fighting song in my head than most of other ones I get in there.
Well enough, I guess. I had just seen the original Old Dark House movie when I chose it. I like the idea that the character of that name was actually played by an old woman.
Because I’m, like, you know, gay and stuff. Gender ambiguity I find playful.
Anyway, it doesn’t seem to be like anyone else’s. Seems to be pretty unremarkable, if the fate of most of my posts is any indication (sinks like a stone doesn’t half describe them).
Maybe I should change to Eeyore…
Nah!
