The only drawback I see is that the user cannot type in an address to locate themselves, they must click on the map.
Other than that it is very slick! The author seems to update it often, adding nice new features (like setting your location on the registration page).
You can easily change any text in the plugin by editing the language file. All in all this is a very nice addition to any community site!
Oh, get your Google Maps API Key here:
Use the same key for both the main module and for your CB/JomSocial plugin (one key for your entire domain, no matter how many plugins you use).
Thank you for your review! Happy you like it, just know about your 'drawback' that CB users can use the geommunity geocoder to get located from their real address. You have to set the geommunity locator plugin in 'readonly' mode for that. ;)
