I've started finishing off some of the help and incomplete web pages. Refer to the site map for an up to date description of all currently available pages.
If you have any requests now's the time to make them. I have in mind the "overall ranking" idea (discussion) and may implement this although have discouraged this and kept the level sets independent from one another til now (see related page help).
I'm going away next week so the new level sets look like being release the week after, probably the 29th.
