As code refactoring continues, I've enhanced the mechanism by which the user can be specified for the main overall stats page for a user:
http://tm.teresco.org/user/As before, you can specify user with the u= query string parameter and it's remembered in a cookie once you do that, but the free text input field has been replaced with a list of all travelers who had at least one clinched segment somewhere in their list file.
I tried it out quite a bit and was confident enough to put it right onto the main site. It could certainly still have problems, so please let me know if you notice any.
I plan to do the same with other pages, where system lists and region lists will be drop-downs as well.
