Basically every discussion with over 50 posts has gone from the subject to personal attacks.
I take your point, but I don't see how letting the thread creator delete the thread helps anything. If anyone wants to talk about the most difficult toccata or the most dramatic piece of music, at least they have a thread for that at the moment ... does anyone gain by letting someone arbitrarily deploy the nuclear option on their own thread? It would just turn every forum member into a de facto moderator of every thread that they initiate.
