Jon Freeman;yes I had thought of that. It seems to depend on everyone's assessment of the situation: i.e. whether the loss of posts is more significant than the irritation of anonymous flamers. I can see why you would regret the loss of musical content, as I would...except registration really IS an accepted part of internet usage now and maybe that is the sacrifice (of privacy and convenience) we all must acknowledge.
Of course I also agree the best solution is for everyone to just, oh, behave! Sadly we all have different definitions of that, too!
