Linking author names to their profile pages, f.e. for Google's rel=author
This extension adds a new input field for an URL to the user form.
The news templates use this URL to link the author's name to the profile page.
By entering the URL to your Google+ profile page in the new field, followed by ?rel=author, Google will show your profile picture next to the Search Result, as well as a link to that profile.
