@BalooUriza @homegrown Only if your user base is one you want to be geographically based. I'm a member of two sites and not by accident. I am in the Americas and have membership in one site that is geographically the closest to me. And the other one is in Germany that is the closest to my interests. But of course it is the purpose of having the site that the site admin considers important that will decide that.
@wbpeckham Pretty sure I covered that in my parenthetical.
