http://smoothentrepreneur.com/?author=1 What file should I edit so that I can add a little author bio and possibly add a picture?
If log into your Dashboard and go to Users, you can add bio information there. Also if your email address that you use on that blog is registered with Gravatar, what ever image that you have associated with it will show up where ever you log in with that email (if they are using Gravatars, which Wordpress does) Other than that, you can use any number of Wordpress Author box plug ins, or just use HTML to make one up in a text box to place in your sidebar.
