It provides about 50 web-based applications including a Calendar, Addressbook, an advanced Projects manager, Todo List, Email, and File manager. The calendar supports repeating events and includes alarm functions. The email system supports inline graphics and file attachments. The system as a whole supports user preferences, themes, user permissions, multi-language support and user groups. It includes modules to set up and administer the working environment. The groupware suite is based on an advanced Application Programming Interface (API). Main project's site was down at 29 July 2010, also information site seems not maintained since 2005, so seems this project is dead.
