just one minor addition to this list... > (ac|co|ltd|gov|mod|net|nhs|org|plc|police|sch).uk
it should also include .me.uk - so list for .uk should be... (ac|co|ltd|gov|me|mod|net|nhs|org|plc|police|sch).uk perhaps you could throw nic.uk in there, but any subdomains of that would be controlled by Nominet... hope this helps Brian
