It looks like a lot of work has gone into this, with quite a few features. These kind of plugins can be difficult to get right as you have to get privacy settings correct, make sure they're easy for users to use, and be reliable. There's still a couple of quirks, like issues with the mini map, and basic things needed like being able to see a user on a map on their profile. But shows a lot of promise to be a great member map plugin and the devs have been very responsive so far so I'm sure it'll continue to improve.
Excellent supported Google based Member map with certain real good features and plans for more. But best - it uses the original location field and so we have no pain with an extra fields. Also top - no use of IPs as location maker... Thanks for that!
