Another thing that could be done with the location detail is the gmt adjustment.
Let me explain:
For example, when you are in russia you got lot of different gmt time depending where you are in russia. With this, you can know what gmt you are and so change the "shoutbox" and forum (and more ?) posting date according to your gmt .

Was it WaC or WLC ?

I remember that map, but can't remember from which clan/league.

I'm currently living in ?Chernobyle
