I've put together the first cut at a tree-shaped forum table of contents, and yes! I have a [/forums/ol/|demo], showing a read-only view of Geek. So it's kind of recursive: This message should show up in the demo as soon as I post it.

It's not finished yet. The most glaring omission is the lack of a way to post a reply. That should show up in a couple of days, as a stripped-down version of tikiwiki's forum post page. Lots of little details need polishing after that.

Added: Speaking of not seeing the forest for the trees, when I looked for this post I realized that the tree is sorted backward: Most-recent post last. Doh.

So, wadda ya think? Is this more like the familiar UI?
