Just added a usermap that shows who's online, and where they are:
See it here: User Map: Chevrolet Aveo forum and owners club - AveoForum.com
It's a nearly "live" map that shows members, guests & search spiders based on visits in the last 30 minutes, I believe.
Thanks to MikeC06 for the suggestion.
I was originally looking for a usermap that lets us voluntarily post pins of our location & usernames on a Google map, but there's there's really no version for vBulletin 4, which we're running. Only for the previous version.
