I was just going to ask FTJ the same thing. I was seeing last poster information on the thread pages all along in Firefox, but it was missing in Camino. The original intent was exclude 'last poster' information from the main page but retain it in the discussion lists. Apparently, in some cases, the code went a bit too far. Anyway, I've changed the CSS to be a bit more restrictive. If you're not seeing changes, try going to the site skin page, hit the reload button, then try looking at a discussion list page. It's a much less drastic step than emptying your browser's cache to force changes to show up, although that's an option, too.
