New version of site

We have a new version of the site up and running, as you can see, involving a new version of the blogging software, MoveableType. (We've been working on this over the last couple of days, one reason for the lack of updates.) One nice feature is that you can see all posts by category. This version permits you to register (using TypeKey, a shared-authentication system). This will come in handy if we run into spam problems or abuse of the commenting privileges. It also will allow you to save your information more effectively and allow to suppress information you don't want to share. So let me know what you think.
