Just to add a bit of thought behind my idea...

If you want to see all the threads about Spain currently there is no easy way to search as no one types "Spain" in the Barcelona thread because it is obvious Barcelona is in Spain. This also requires you to search for each individual city one by one which is tedious instead of just searching "Spain".

It ensures some organization in the European forum without creating sub-forums.

If the thread was a general European thread (eg. Cell Phone in Europe) the country would not *have* to be listed in the title.
