Hi Gerald,
I don't know Russian, but I'll take a crack at it. (To paraphrase Sam,
I can understand Russian as well as the maniac that invented it, but I
talk it best through an interpreter).
My guess would be that "marktvenovski" would translate as "having to do
with Mark Twain," or, more succinctly, "Twain-like."
Thanks for the word-sleuthing opportunity. I like "marktvenovski" so
well, I'm going to go out and have it engraved on my letterhead.
