MGF: mod Google+ Feed
Google+ Feed (Mod_GoogPlusFeed) is a module designed to embed your Google+ posts into a Joomla site in the way that mod_btwitter does for Twitter. The core principle of the design is that it shouldn't contain un-necessary chrome and shouldn't slow page load.
The module can also display all posts within a Google Community - Simply specify the community ID instead of a user ID!
The module is available from Bentasker.co.uk
