Citadel.org - E-mail & Groupware Solution

Citadel is a software solution that caters both for those looking for e-mail and groupware in an easy to install and configure package. Its full features are listed on the main page of its official site (www.

citadel.org), and these include shared calendaring and scheduling options alongside instant messaging and multiple domain support. Citadel itself is presented using an AJAX-style web interface, and it has multiple front ends to accommodate the needs of different users.



The site includes screenshots and documentation dealing with concrete issues such as how to customize the program, and a developer manual that can be consulted for reference purposes is also part of the premises.

Information on how to install the software is likewise featured, and a one-step installer that automatically downloads and installs the full Citadel system on any computer is provided. This goes by the name of “Easy Install”, and it can be found under the “Download” heading.

It is also interesting to point out that Citadel is open source software that is available to every person who is interested in it.
