There is no facility to request re-registering yearly, so that one is impossible anyway.
As a little guide, visitors IP numbers (their unique connection/modem details) can give an indication of their location - if they are on geographical IP's: co.uk and .com.tr are geographical, .com & .net aren't etc.)...
Anyway, in October 2005 there were 5 times more UK visitors than ones from Turkey to this website. A year earlier, there were 6 times more UK than from Turkey - so a swing to the Turkey me thinks.
