I use Mid-Century and MTOS 4.21 (I know they have 4.23, but I don’t have FTP access). I’d like to at userpic functionality (which I did) from [http://www.movabletype.org/documentation/designer/publishing-comments-with-userpics.html]. But when I do a test comment, the comment’s userpic is at the very side of the comment, making it look ugly. How do I add a border and move the userpic to the right-hand side of the comments (like http://mt4.juneeonline.com/babble-on/archives/2008/06/add-a-menu-bar-to-mt-themes.php#comment-163)?
Oh, and to other Mid-Century users, it’s better to put the userpic code in Individual Comments, so the userpic doesn’t show up above the comments.

The site you refer to doesn't use Movable Type's userpic template, but uses Gravitar.
You'll find a tutorial on how to get it working here:

Since you already have userpics working, it might be just a matter of changing the stylesheet to add a border, and float the image to the right of the comment field.
