Check out our Flash demo of WebCit 6.40! This new version was released today, and it is an upgrade that introduces many new features. WebCit is the web-based front end to the Citadel system. It now supports numerous AJAX-style features, such as the ability to drag and drop messages between rooms (or folders), an improved rich text editor, an improved two-pane message viewer, additional bulletin board options, and a left-side menu bar that can toggle between the main menu and a collapsible room list.
Additionally, WebCit can now run in three different languages: English (US), German, and Italian. More translations are on the way. If you don't see your language listed, you can volunteer to be a translator.
If you're looking for AJAX groupware that is easy to install, easy to use, and easy to live with … look no further.
