I must confess to being one of the first to post a 'funny answer' if something witty occurs to me. The difficulty is gauging the response when one is not face-to-face. Sometimes this leads to an hilarious thread, at others it causes great offence. I think that if we all followed the Ed's instruction, 'If you don't know the (correct) answer, don't post', many questions would remain unanswered, leaving the OP to feel that he/she was not part of this community. The logical concomitant of this is that all of Molly's threads would consist of a question and no answers! (I'll probably get into trouble for sayig this).
