As the President of the local IPMS chapter here in Little Rock (Central Arkansas Scale Modelers).... I'd like to throw in a quote by our Secretary from a board meeting a few months ago that I think sums up the last 4 pages of responses...
"Modelers almost by definition are near sociopaths, otherwise they wouldn't prefer to happily sit alone in a room for hours without speaking to anyone. So it stands to reason that if you throw 30 of them in a room together you couldn't possibly expect them to all get along. The nice ones will fake it... "
Our secretary is a criminal psychologist by the way...
Ok, that's all... carry on!
