Actually, thinking about it a bit more - your approach/thread title excludes non-UK urbanites who are living in their own countries. There are quite a few Irish, American, Canadian, Aussie, Kiwi - and other - urbanites who it would be good to hook up with or ask about their home towns/countries. You seem to have a too narrow view of urban75 and the thread like this may well reinforce misconceptions that this website is a "British" one. It is in fact international (albeit primarily uk/british/anglophone).
The thread should simply be "The location of Urbanites worldwide" with the only group excluded being urbanites who have never lived outside the UK (on the grounds that as the largest group this is the 'default'). In fact this is how you have compiled your list (with the '3 months' criteria) but it is not how the thread is entitled and doesn't correspond with your comments in some of your posts on the thread.
(edit: you could even argue that it would be cool to have a list of where urbanites were in the UK, so that people could hook up with other urbanites when they travelled around the UK. There is currently no way of looking at a list of 'locations'.)
