Significance of CheckAuthorName?

Sep 27, 2008 at 6:00 AM
When adding a comment to a post, if you're not logged in, then the CheckAuthorName JavaScript function is called to make sure you didn't enter the same name as the author's name.  Is there any significance to this?  The only thing I can see it used for is determining if the "self" CSS class should be applied to the div containing the comment.  If this is the only reason for CheckAuthorName, I'd prefer to find another method of connecting the comment author to the post author (not sure what that would be though!)
