Well, LeicesterProperty.uk dropped last night, which given Leicester's size might be useable.
Also LincolnProperty.uk
BrightonProperty.uk
BelfastProperty.uk
GuildfordProperty.uk
ChelmsfordProperty.uk
All these dropped last night.
But no .co.uk to go with any of them except ChelmsfordProperty, and besides, doesn't RightMove dominate the online property market? Not my field!
