This plugin allows an easy integration of Google Maps on your pages or posts.
It uses the Google Maps API version 2.
In order to use the API, Google requires that you register a key for your site domain. In the version 3 of the API this is no longer necessary.
Yes, I'm on it. However this version doesn't support yet some of the features that we have on the version 2 (like the tabs on the InfoWindow). But soon this plugin will be release, probably with the name WP_GMaps3.
