" Is there any way that Max can block his IP address or summat?"
I 'believe' that blocking IP addys usually involves blocking whole domains...so that it might stop 27 totally innocent folks also...

What I wish for is an 'ignore' button, so that I could make a list of those whose posts I don't want to read. They do this in 'live' chat rooms, but it's probably too much trouble here.

What I REALLY wish for is for Gervase's suggestion to be implemented...*grin*....This guy must spend 16 hours a day 'researching' this stuff and typing his warnings.
