What is Horde Groupware?


Horde Groupware is a free, enterprise ready, browser based collaboration suite. Users can manage and share calendars, contacts, tasks and notes with the standards compliant components from the Horde Project. Horde Groupware bundles the separately available applications Turba, Kronolith, Nag, Mnemo, Gollem, and Trean.

It can be extended with any of the released Horde applications or the Horde modules that are still in development, like a file manager, a bookmark manager, a forum or a wiki.
