Hey if you just make a contraction of omniscientnot, you could be S’not.

Hey, now!
Let’s see. You’re a Canadian. I suggest Dudley Dooright. (From the same people that provided me with the inspiration for my name.)
Oh yeah. Also, wanted to say that I really like The Great Pumpkin, too.

YO-HO, ME HEARTIES! ALL HANDS ON DECK FOR THE MUSICAL BATTLE AT SEA!

The Great Pumpkin would be a very nice handle. Plus it would prove linus right all these many years!

How about “The Poster Formerly Known as Omniscientnot”?
“The Pumpkin King”?
“Cecil’s Number One Fan”?
“Punch Me”?
“The Mentos of Death”?
“A. Nonymous”?
“Batman”?
Is “Bug Vomit” still open? 
I don’t know, omniscientnot seems to say it so clearly…the antiOmniscient. But of course, I can understand your desire to not be confused with your sometimes evil twin (emphasis yours). At the same time, your quest for a new identity seems to be lacking…energy.
Allow me to suggest the following for the sake of argument: perhaps you subconsciously recognize that individuality and uniqueness are over-rated. Perhaps you merely want to avoid confusion with Omniscient - and confusion with a more luminary and respected member of our board would still be okay? In that vein, then, please consider the following noms-de-screen:
Satin
MrFidelity
Polycod
menhattan (or madhattern)
Once you get rolling, it’s obvious that there are thousands more where those came from. I’m sure you can find one that fits.
RealtyChuck (or RealityUpchuck)

As for myself, I am going to take inspiration from your quest, and from kellibelli’s post about getting busted Doping at work, and pick a new screen identicon.
In my case, I am not only emoticon-challenged in my writing, but that feature also carries over from real life. (Even in face-to-face situations many people have difficulty understanding I don’t always mean everything I say. In addition to my straight-faced expressions of wry, nay black, “humor” and unconventional “try-this-on-for-size” opinions, I was clearly put on Dirt to be a Devil’s Advocate. (Satan? Openings and compensation structures, please.) I always see at least three other sides…)
And so I become, so far as I know, the first member with an emoticon for a name. {:-Df, that’s me. Pointy head; big, foolish grin…clearly worth every dollar I paid the consultant.
Now back to our regularly scheduled programming. Omniscientnaut, I didn’t mean to steal your show.
Whaddaya know? It works. And better than the version just above, which caught a line feed in the chops.
To me, there is only one possible answer:
“The Doper Formerly Known as Omniscientnot”
The IQ of a group is equal to the IQ of the dumbest member divided by the number of people in the group.
Sorry about that non sequitur post folks. I have no idea how it got here. It was for another thread… I must have had two threads open at once. Or I was drinking two beers at once…
As to the topic. I like Bob. It’s simple and easy. Or you could have 1800gethair. That is rather weird!
Best!

{:-Df : A couple of clarifications. You say:
Well, actually, it could be the other way around. I have no problem with being confused with anyone of the Teeming Millions. As for the “sometimes evil twin”, I’m afraid the emphasis is yours and not mine, unless you’re referring to the fact that, in my posts, I usually refer to my twin, in jest, as being sometimes evil.
Well, I did take the initiative of putting up a thread and asking for the Teeming Millions’ opinion and possible suggestions for a new handle. Even went so far as to suggest a few myself. Actually, the response so far has been great, beyond my expectations.
LOL! Afraid you’ve misread me. Or my reasoning was perhaps a bit nebulous. I’ve got nothing whatsoever against individuality and uniqueness: in fact, I do cherish mine. And I’ve got absolutely nothing for or against being confused with Ominiscient (see supra). The same observation would in fact apply as regards “a more luminary and respected member of our board”.
The reasons, as simple or as complicated as they are, can be found in the first two paragraphs of the OP. Come to think of it, perhaps I am making too big a deal of this. We’ll never know.
P.S.: Should we still call you David Forster, or The Poster Formerly Known As David Forster?
Where on God’s green earth did David get that?
I wish he would clarify what the hell he meant! Me personally? I would love to be confused with either of the Omni’s. They are both well respected and loved roundabout these parts!
-Frankienot. Anyone confuse me with Omni-not?
DANG, what’d I do to get treated so serious-like, alluva sudden?
Not only could be; IS. I just figured you shoulda left the qualifier off. (The one time I had dealings with Omniscient, s/he acted the perfect part of a troll - but that may have been an isolated incident and was partly my own fault, and Omniscient may be otherwise a fine human being. Just not perfect, like the rest of us are.)
You did. And don’t explain yourself. It’s a Fine Idea. You did good. And the thread’s something to be proud of, too. (Drinks for everybody, on me!)
Maybe I shoulda said “losing steam.” It just seemed to me, as I went home last night, that your thread had dropped too far down the list, as if people were losing interest. I Wuz Wrong. (But I’m still in the perfect group, right?) But mostly I just needed a fake reason to pretend you were suffering ennui due to a subconscious recognition of the False Promise of Individuality. (See? I told you I was emoticon-challenged. Of course, now no one will take anything I say seriously…) With more thought a better segue would surely have occurred to me.
Anyway, omninaut gets my vote.
Since I said it, it’s kinda been growing on me. Multiple interpretations possible, retains a link to the old identity, it’s practically what a number of people call you already…think it over. At least the price is right.
As fer me, just don’t call me Late For Dinner. (And speaking of which…gotta go!)
P.S. “The Father of Liberty” is now literally true [9/5/99, 20 inches, 3195g] but, though I didn’t think of the appellation myself, yet I am forced to admit it’s too egotistical even for me.
(The one time I had dealings with Omniscient, s/he acted the perfect part of a troll - but that may have been an isolated incident and was partly my own fault, and Omniscient may be otherwise a fine human being. Just not perfect, like the rest of us are.)
Uhhhh…it must have been my evil twin.
Actually, a poster who has yet to determine what sex I really am (I usually make it pretty damn clear, not to mention the profile) surely doesn’t have the grounds to go casting insults. Do a little research first. Or feel free to flame away, it’ll be entertaining.
My vote goes for Jack O’Lantern. Second is the Great Pumpkin, but if you are seeking to come across as more humble then you should avoid names with “Great” in them. Besides, we could all refer to you as Jacko. Just fun to say, Jacko. Hundreds will respond to all your posts, just so we can say “Well, Jacko, I agree with you…”
