How is the locate done?
I have constructed a database using Battlefield 2 stats. This DB has nearly all PR players and their nationalities. When user loads the View All menu in PRSpy these nationalities are fetched one-by-one from the DB. The orginal source for this database was following web page: EA ::Battlefield 2:: Player Search
Why did you create this?
Out of curiosity, I wanted to know how common PR was amongst my own nation and which nationalities like to play on which server. As a bonus this allowed me to locate people from my own nation and see if those people are the ones I like to play with. This was purely created for myself and I couldn't care less if somebody else doesn't find it useful.
