You mean a humor forum? We already got it covered.
One-liners (First magician: Who was that lady I sawed with you last night? Second magician: That was no lady, that was my half sister.") go in the forum called MPSIMS.
Satires (“What foods these morsels be!”) are a form of arts and entertainment, so go in Cafe Society.
Question/answer jokes (like Knock-knocks, or “How many Swedes does it take to screw in a lightbulb?” “Swedes are too large to screw in lightbulbs, they screw in saunas.”) go in IMHO.
No jokes are allowed in the Pit.
To expand on what C K Dexter Haven said, we are generally loathe to create new fora until and unless a definite need is seen by the mods. This need must make it more difficult to moderate the other fora, and must make it more difficult for members to find and post interesting threads. It really takes a pretty obvious deficiency in our system to make a new forum a reality. Suffice it to say, a single thread in ATMB isn’t going to cut it.
Cafe Society is the only forum created during my time as a member here. Prior to CS, threads about the arts and entertainment were spread out over four fora and pretty unsuited to each: Factual questions (“Who played the Man with No Name in A Fistful of Dollars?”) ended up in GQ, polls (“What is your favorite Star Trek series?”) ended up in IMHO, general kibitzing (“Voyager is coming to DVD! Whoopee!”) ended up in MPSIMS, and rants (“That last season of E.R. really sucked!”) ended up in The Pit (back before the Pit mods really cracked down on non-Pitworthy rants). This wouldn’t have been a huge problem, in and of itself, but there were so many arts and entertainment threads that they crowded things off the front page in many fora (MPSIMS was really hopping for a good while, with threads disappearing in minutes) and generally made organization and moderation a royal pain. Then CS was created and the pressure was alleviated.
That is the level of need you require to get a new forum created, and I simply don’t see it in the SDMB as it stands.
I got it. Had to read it twice, which shows how slow I’m becoming, but at least I got there in the end.
A humor board, even here, wherein dwell so many and varied wits, would bite the dust. True hmour is almost invariably generated when it is not the end of the discussion, but a by-product, whether deliberate or not.
