The best console based BBS package around!
DayDream BBS runs on my Linux PC as well as on an old Amiga 1200 with NetBSD. It is very flexible, almost 100% customizable and offers a lot of "modern" features such as FTP up-/download capability. The only thing missing is an integrated chat system, but this can be realized using ntalk as a BBS door.
a great product

An open, cross-platform journaling program.
A scientific plotting package.
