yes indeed i have had a fair few run ins with the carphone dynamic ip we don't seem to have a way to stop such accounts from as you say troll talk pages and being unable to edit but such accounts are disruptive i should have ignored him personally i support only accounts and no ip edits that would go a long way to stop many of the vamdalism and socking issues but it might make it a tad quiet best regards tfow nice to see you again
