By "complete looks", do you mean the page layout, or the colors/graphics?
Page layouts can be distributed with template files, like I've done with Compact Headers & Footers. These are just done with the actual template files (ie. public_forum_summary.pl).
Colors/graphics schemes can be distributed via style settings files, or by style settings explanations, i'll call them, for lack of a better word. In our Design Tutorials database (up at the top), we have a page that lists several color scheme suggestions that you can enter into your style settings control panel. Alternately, Infopop does now allow distribution of the actual files that control style settings. However, this decision is relatively new (and/or not very well known), so I have no clue whether files of this sort are actually being distributed right now or not. If you do find some, you can open the Styles subdirectory of your non-cgi folder, and copy the file you found (should be something like vars_style_#.cgi) into that directory. It will have all applicable settings preset. But like I said, I'm not sure if you can actually find these files yet.
