Speaking of things that have been on the TODO list for a while, the Thinking Stuff User Manual has now been released. It's available on the Downloads page.

Unfortunately I can't take it off the TODO list yet, as it's not quite finished. But it's more than 100 pages, so you have plenty to read already.

Man that took a long time. And I still have the biggest sections to do :-(

Incidentally, I also updated the Installation, Upgrading, Removal Guide as well, but just some minor changes.
