Indiana Jones. in GQ (about archeology ) and MPSIMS ( I Hate Snakes.)
Marcus Didius Falco - GQ (about Rome)
Ford Prefect: MPSIMS ( Travelogues) IMHO. (Best uses for a Towel)
Chip, the main character in The Corrections. He’d be posting in MPSIMS about his sexual escapades between teaching college courses and then asking questions about his dad’s Parkinson’s in GQ.
Cthulhu would be interesting - it would be nice to have the perspective of an eldritch terror from beyond.
But on second thought, He would probably just piss of Lynn and get banned. 
Augustus McCrae of Lonesome Dove
MPSIMS: How to get a poke for only $50
Captain Ahab
The Pit: You just can’t get good harpooneers these days.
The Pit: Hunter S. Thompson and Ken Kesey are musts. Until they passed out cold and posted the random assortment of letters resulting from their heads hitting the keyboard with a resounding thud…Or got banned for giving detailed instructions for manufacturing and/or copping drugs.
Almost any of the characters from Spider Robinson’s Callahan series, but if I had to pick only one it would be Jake Stonebender, the narrator.
Captain Jean Luc Picard from Star Trek, TNG.
He’d be awesome in GQ and GD. Especially about all things re: archaeology. He’d probably make a great moderator as well. I can see him posting a few good zingers in MPSIMS too.

[li]Sherlock Holmes[/li][li]Tom Swift Jr. Boy Inventor[/li][li]Batman, if he’s prepared.[/li][/ul]
He did, and he was.
Dirk Gently would definitely be fascinating to have on board. (GD, GQ, IMHO)
Especially if Sherlock Holmes was on board to.
Can’t you see it in Great Debates?
“Once you eliminate the impossible…”
“I prefer not to eliminate the impossible…”
Thursday Next (The Eyre Affair and sequels):
Pit:
They eradicated my husband!
GD:
Is this ethical: Changing books so the ending is better liked.
IMHO:
I need a vacation. Can anyone suggest someplace besides the Well of Lost Plots?
**shirt, brown, honesty ** —
would you care to explain the basis of your name? :dubious:
Emma Woodhouse, strong willed, flawed, infuriating and yet endearing. (Emma)
Francie Nolan, romantic, yet sturdy and practical, needing “truth”(A Tree Grows in Brooklyn)
Scout Finch (ok so we’ll taker her when she’s old enough), unusually smart and articulate for her age, a reader, sensitive, tomboy, stubborn, spunky and opinionated. (To Kill a Mockingbird)
Atticus Finch, virtuous, standing up for what is right, tolerant, patient, tough, courageous, fair minded. (To Kill a Mockingbird)
Edmund Black Adder
Maybe Baldrick, as sometimes he had cunning plans.
Withnail, I’m sure, would have many opinions about acting and films and recreational substances for Cafe Society
Either Bertie Wooster or Jeeves. Why not both.
Bridget Jones
The Baroness of Cobra vs. GI Joe fame.
Because—[list=a]
[li]She is the Chief Of an Intelligence agency.[/li][li]She is a combat pilot.[/li][li]She has strong, alternative political beliefs.[/li][li]But mostly, because she is an Eastern European Schoolmistresses/Dominatrixes in a black leather catsuit. And you just can’t have too many Eastern European Schoolmistress/Dominatrix in black leather catsuits. 
[/li][/list]
Definitely Jubal Harshaw. He knows everything about everything.
R. P. McMurphy–for the Pit. 
Mary Poppins. Not only is she practically perfect in every way, but she’d give some great tips for packing luggage.
Santa: Labor union debates (GD). Funny elf stories (MPSIMS).
Hamlet: Conspiracy theories (GD). Share Your Dysfunctional Family Stories (MPSIMS).
Stoppard’s Rosencrantz and Guildenstern. Word games (MPSIMS).
Done!
Who is John Galt?
He’d OWN Great Debates, tho we’d all like Francisco d’Anconia much better.
