It was funny to see him try to play quake/doom, and then walk in a straight line. :) John -- # John Madden weez@xxxxxxxxxxxxxx ICQ: 2EB9EA # Sys-Admin / Webmaster, Avenir Web: http://avenir.dhs.org # UNIX Systems Engineer, Ivy Tech State College # FreeLists, free mailing lists for all: http://freelists.dhs.org # Linux, Apache, Perl and C: All the best things in life are free!
