Well, in the end, it actually boiled down to a few choices. Of course, I could have kept the handle intact, as several of you have suggested. But that would have run at cross purposes of the initial thread’s intent.
So, after due deliberation, I have decided to discard the runners-up imnotomni (nice alliterative-quasi palindromic quality) and The Great Pumpkin (less pompousness combined with deceptively insouciant innocence) and to opt for the more familiar (albeit admittedly more “bland”) omni-not. I guess I will have to live with this momentous decision for the rest of my life and assume the heavy burden of perpetuating omniscientnot’s memory.
Many thanks to the regulars and newbies for their input. The response was greatly appreciated and went beyond my expectations.
P.S.: Merry Xmas, Omniscient!
PP.S.: Durnovarianus: I guess “Ralph” is yours for the asking…Just check with Stoidela first: she might have copyrighted it in the meantime. (Could be that “putrid” has his/her eyes on it too, which would be understandable)
