As far as number of replies, it had to have been one I put on the old board (partly in response to complaints about off topic threads) about how happy I was to have come across "real" people on a gaming message board. Totally blew away the sterotypes of D&D and AD&D players I had developed as a callow youth.
In terms of success, any game related post has been tremendous for me. Someone has always (well one exception) responded with courtesy and respect - no matter how many times my question has been asked. In addition, several (Memnoch, Black Knight, Sir_Tainly, Donut, Jerome, Gabriel, Hesperex... shall I continue?) have provided most helpful links when they felt it might be inappropriate to resuscitate the dead horse I was beating.
