Citadel is an advanced messaging and collaboration system for groupware and BBS applications. Users can connect to Citadel using any telnet, WWW, or client software. Among the features supported are public and private message bases (rooms), electronic mail, real-time chat, paging, shared calendaring, address books, mailing lists, and more. Unlike other collaboration servers, Citadel provides its own data stores and is therefore extremely easy to install; you don't have to "bring your own" email and database because they're built in. The server is multithreaded and scalable. In addition, SMTP, IMAP, and POP3 servers are built-in for easy connection to Internet mail. Citadel is both robust and mature; it has been in production since 1987.

The LDAP connector has been updated with a new schema, and now works cleanly with the latest version of OpenLDAP. Extensive testing and tuning has been performed under FreeBSD. The Citadel system should operate much better on FreeBSD (as well as Linux). Support for "webcal" (iCalendar over HTTP/WebDAV) has been introduced. You can now use calendar clients such as Mozilla Sunbird, Apple iCal, and Ximian Evolution with your Citadel calendar. Web calendaring now supports "bubble popups" to show the details of any event you hover over with the mouse.
