No link to author's posts in meta data

Love your theme!! I noticed in both Archive listings and single post that under the title, in the post meta data, the author is listed but there is no link on the author’s name to all posts by that author. There is however, a link to the categories it’s under.

Is there a way for me to edit a file to add a link to the author’s name to all posts by that author? Or, would that be available in the premium version?

Thanx in advance
