Art started Citadel/UX in October of 1987, and though it does not contain
any code from other Citadels it is very similar to Citadel-86. Art has
done a great job creating a UNIX based Citadel that is more than a
newsreader. Though you can gate Internet e-mail and newsgroups. This
system contains many of the features found in DOS-based Citadels. As
with a lot of UNIX software Citadel/UX is freeware and it's been tested
on many flavours of UNIX. Art can be reached via Internet email at
