Edit Font Sizes?
 

Where would I go to edit the size of the font for the category titles as well as the member's user name in the comments, I would like it to match what is in vBulletin postbit. Also, I see in the template that it usually says 'class=smallfont', what would I have to change this to so it would match the font style that a member's name has in a normal vB forum post?

Look at the photoplog_cat_bit and photoplog_rate_bit templates and try class="bigusername" instead.
