What do you guys think?

yeah i like this
maybe it can say the name of the country too

this would help in a lot of discussion threads that are based on current and past geographical issues

Simple, nice and functional, i like it. Maybe only a little bit smaller, like the one you have ingame.

Supported.

I've been wondering from alot of forum only people what country they are from.

So yeah, could be useful.
