[LON-CAPA-users] loncapa forgetting submissions?

I'm guessing that the "View Recent Activity. . ." link is a 1.3.x feature?  We 
don't see it here in our stone-age 1.2.x installation.

There's bunches of stuff in /var/log/httpd/access_log, but I don't see 
anything there to positively identify one student over another.  I've also 
looked in /home/httpd/perl/logs/ , but again, I don't see many entries that 
specify actual users.  Is there someplace else I can look?

Thanks for your help.
