One parting note. Some of you may be wondering why it's called "version 3" when it really seems like version 2. To us, it really is version 3 -- it's the second major rewrite of the system. The first major rewrite did not, unfortunately, involve the client, which is why it remained at version 1.x. The server and web site are both in their second lives right now, so for consistency the current development cycle -- including the client -- is being called "version 3."
