Citadel is an advanced client/server BBS program for operating highly interactive sites, both on the Internet and over dialup. Users can connect to Citadel/UX by telnet, WWW, or client software. Features supported include public and private message rooms, e-mail, real-time chat, message forums,and paging. The server is multithreaded and can easily support a large number of concurrent users without arbitrary limits of messages per room, rooms per system, etc limited by the size of data structures. Both POP3 and SMTP servers are built in for easy connection to Internet mail. Citadel/UX is both robust and mature, as it has been developed over the past twelve years.
