I tried to automate it with my mcelrath.org mirror but the problem I had
was with authentication, I think.

In every instance where someone has made a "backup" site that I have

they aren't the same, causing further confusion.

For some reason bizarre physicists do this a lot.  I think it's a bad

Links to the other site for large downloads would be a good idea though.
