Add Categories, demote tags from gaurav theme

The gaurav theme shows a "hot tags" listing the top 30 tags, which doesn't look good if the blogger has just started out with a few blogs (or is not even using tags.) Either remove the hot tags and put something else there, or only show the tags once a certain number has been used by the blog.

Also, Roller provides weblog categories, add a category listing to the blog by default. If the blogger doesn't use categories, he can get them removed from his copy of the theme.
