themeing the buddy of uid blog on profile page

Hi michelle, Advanced Profile rocks!

Quick question, I'd like to alter how buddies are listed in in the buddy of uid blog on the profile page. Currently it shows the image, then the username right below it and puts a box around the package. Where's the code that generates this theming? I ask because I've noticed that the user name is a link....but its busted. The links all lead to user/ isntead of user/uid. The photo links work fine. I'm guessing there's some code somewhere that generates this link, but I don't know where it is. Also, I'd like ot be able to shrink the size of the boxes etc.

So where's the code that generates the out-of-the-box theming for this block's contents? I've hunted around in the advanced profile files but can't find anything that rings a bell. I'd really like to get these user links fixed.
