OMG! I was just wondering if there was M*A*S*H SLASH, specifically Trapper/Hawkeye and I came across this on friends-of-friends. My M*A*S*H discovery was similar to yours, except I saw Trapper first, then BJ.

Thankyou so much for the essay and fic links. My sister just brought me back a pair of M*A*S*H pj pants from America, so well known is my love for the show.
