I cant believe this - I had a linux box doing IRC, httpd and mailing lists . It was cracked into a wiped, and the cdrom the linux was on had a bad spot and couldnt be restored. I put freebsd on it, and not only is it much more responsive, but it was so much so that I was able to add functions, and cancel a hardware upgrade. On Wed, 13 Aug 1997, Jay D. Nelson wrote: > Hmm...
