You might want to wait a week or two, I'm coming out with beta 3 which includes;

• Full, and I mean full site overhaul. Nothing spectacular with the new design, I just needed to redo the user interface to support a variety of new features and abilities of Tuatara.
• Redesigned administrative interface - again, to support the expanding feature set. Wanted to make something a little more fluid too, so the tables/directories didn't need to be so tight.
• Much more in depth documentation
• Some improvements to the templating engine
• Minor overhaul of the member modules, additional security and various various bug fixes across the board.
• Four add-on modules, including a headlines system (prelim to a blog module), project tools (minimal at this point, just includes a feature request and bug reporting system), comments (can be dropped into any page with two simple lines of code), and a bbcode parser which is primarily for use by the comments system, but can be downloaded and used on it's own too.

Oh, and it's pronounced two-ah-tara
