Tetra-WebBBS is a Web-based bulletin board.

Tetra-WebBBS is a follow-up of WebBBS, a web-based bulletin board (or forum) system originally programmed by Darryl Burgdorf. Darryl`s development of WebBBS stopped at version 5.12 back in 2002. In 2006, a team of people, unrelated to Darryl, started working on their own updated version, named Tetra-WebBBS. Tetra-WebBBS is released as freeware and allows for a very flexible, customizable setup and offers a wide variety of options to both the administrator and the users.
