Why is anonymous posting allowed?

Say it all. Can we have posts only from registered users?

admin has already answered this. the amount of abuse is statistically 40:60 against REGISTERED users.

That there is better chance of people posting as guests who MAY then join

but of course - admin will listen to any considered debate about the issue

Then abusive posters should be suspended. There is one user who posting aggressively and abusively all the time. It would be easier to ban/suspend rather than delete all the crap.

that is done also, but that is harder to do

but trust me it has been done in the past and will be done in the future
