Custom avatar not working in recent comments (Wordpress)
===

So I made this plugin that changes the avatars in wordpress and generates a specific image depending on the user's e-mail address. 
The plugin works great in normal comments (using the global $comment) to retrieve the commenter e-mail address, however, in the recent comments widget it doesn't. I'm guessing that the $comment object doesn't change for a "recent comment" therefore it doesn't contain the commenter e-mail address.
So my question is simple: how do I get the commenter e-mail address in the "Recent Comments"?
Any suggestions would be greatly appreciated!
Thanks a lot!
