A lot of people with my (real first) name like to use their actual full names if this list is any indication:
MICHAEL HOOVER
michael b
Michael Brennan
Michael Corleone
michael crts
Michael DiNapoli
Michael Ellis
michael erard
Michael Faldeglim
Michael Fleming
Michael Fonda
Michael Giraud
MICHAEL HUMPHRIES
michael hunt
(searching with just four letters, the minimum for similar names, gives the same list except that the first three are micha3l6w98, michae210, and Michael).
The closest to me are “My Darn Snake Legs” and “Earl of Sandwich”
Cosmo Smallpiece
Cosmo’s Ghost
cosmo2001
cosmo88
CosmoGirl
CosmoKLennonJ
cosmokramer
Cosmopolitan
cosmos
cosmoscorbin
Cosmosis
cosmoski
cosmosven
now I have to look them up, dam it.
El with-an-underline turns up the following, although I don’t recall ever seeing posts by any of them.
El_chupacabra
El_Conquistador
El_Danger_Mouse
el_eureka
El_Gordo
el_mono
el_nombre
el_paco
el_pey
El_Spectre
el_teso
I’m pretty sure there are a bunch of El without-an-underline posters, but I’m not sure how I could retrieve them with the three-letter limit.
All I can think of offhand is that you’d have to try “el <space> a” and go down the alphabet.
As an old boss of mine used to say about some of my projects: “That’s too much shuffling of the dishes for the victuals involved.”
There’s a Crown Prince of Irony somewhere.
I’m not pissed. I beat you by like * over seven years*, and you post way the hell more often than I do.
Totally different post personalities, if ya ask me.
Tripler
. . . and you have one more vowel.
The only confusion I ever get between **Tripler **and TriPolar is trying to remember which one puts the funny tag line after the signature.
Maybe that’ll help me remember. 
-D/a
I won’t list them all, but there are a large number of “Miss” somebody-or-others who post here. I’m surprised that none of the other Miss Somebody got into this thread before me.
That’d be me. Started doing that years ago. . . It’s kind of. . . expected of me now, as if I’m actually doing the posting and it ain’t some imposter.
Tripler
Hi, I’m Tripler and I authorize this message.
I’m not imposting. You post so infrequently I never saw your username in the years before I became TriPolar. I also should have searched the name and seen it’s a nickname for people diagnosed with both BD and BPD. I’m far more warped than that
I first noticed you about a year ago, and then recently someone in GD made a mention that we weren’t the same person. Well I think we’re not anyway, hard to know anything for sure
TriPolar
Hi, I’m TriPolar, and Tripler did not authorize this message.
Not spelled the same, but I’m sorry PlainJain. Not only do we dislike each other, but I didn’t even think of her when I did this.
:o
From the NOC part:
NoChargePoker
Nochilus Rannsom
nochristenbury
nociorrondima
Nocktober
noclue
NoClueBoy
nocojoe
NoComment
NoCoolUserName
Noctifere
noctifurnace
noctilucent
Noctolator
Once I get to the L, there’s just NoClue and Me.
I remember Tripler. I knew TriPolar wasn’t Tripler. Trip was also Captain Archer’s* friend.
*AKA in SDMB Ent threads as Quantum
So wait. . . did you change your name from something else then?
Now you’re imposting. Or mimicking. I don’t know which.
Tripler
I’m so confused. Did I authorize this or not?
You guys are such a Tri[pP]..
-D/a
I’m D/a, and I’m looking for someone to authorize this message.
etvander
etvxmhir
I have no idea of their status here.
No one else starts with JPN, so I searched JPM and JPO.
