Welcome to the haxxed.com Citadel message board. Citadel is a line of BBS servers with a long and storied history.
All users are able to freely create rooms, just like on a classic Citadel BBS.
The classic terminal client is available via ssh by connecting to bbs@haxxed.com
If there is interest, full support for classic Email services can be enabled, including IMAP/POP3.
Don't be a jerk, and don't abuse the system.
