Hey gang,

* I've fixed the query for the installfests.  The front-page notice
  should be there until closing time

* per shank, clicking the logo takes you back to the front page

* I've put in the custom 404 page that Fearless Leader made.

Wheeee,

   hours. Not as good as the time I stayed up 7 days straight
   though. That was a religious experiance man. God looks like Max
   Headroom, man."
