If it's any help, I found this guide really excellent (http://community.livejournal.com/thefulcrum/27856.html), and grrliz has lots of nifty mixit layouts to pick from. The only problem I've found is that the the usernames do disappear as well, but the fix is very simple and can be found here (http://dw-styles.dreamwidth.org/5062.html)

Sorry for the ugly links. I suck at html tonight.
