Hi,
When an Author/Admin comments on a post, Thematic puts the author username in the class of the comment.
For example, if the user is "admin" , a class is added to his comment as "comment-author-admin".
Many users change the name of the WordPress Admin user name from the default to something that is not easy for others to guess or crack. This adds a layer of security. Unfortunately, Thematic reveals this username in comments classes. So for example, if someone changed it to "secretadmin" the class will show as comment-author-secretadmin.
I didn't see this in the class TwentyTen theme, only with Thematic.
Please fix this security problem.
Thanks.
