Is it easy to set up? Definitely Yes.
Can I link from Author in an article to the Author profile with a list of that Author's articles? Yes
Can I display an Author box below the article? Yes.
Can I display a list or blog view of Articles by a particular Author? Yes.
Does it support Google Authorship? Yes.
Is there a module that will display a list of Authors? Yes.
It even has a plugin to support automatically adding a user to Author List on registration if that user is set to a certain permission level.
The only reason I didn't give this 5 stars is because there are a couple of other features I'd really like to see. But that won't stop me from using the extension or recommending it to others.
Once I figured out how it was supposed to work (no documentation), it was pretty simple. Simply publish the module in any position on your home page or any site page, and make certain it is completely enabled. When a visitor comes to that page, the Age Check form will pop up with a colored "veil" hiding the rest of your site. (You can set opacity for the veil.) If the visitor enters the right date to meet the age check, the visitor is directed to your site page. If the age check fails, the visitor is redirected to a url you specify.
On the other hand, I can't use this module. I need to customize the look and feel a LOT more than the module allows. The way the php files are encoded, I can't even make my changes there.
