All teams, whether corporate or social - need a way to share information: Documents, calendars, ideas and contacts; a forum for ongoing discussions, and a place to store shared resources such as text, images and bookmarks.
Team collaboration tools, or groupware as they have become known, offer all of this functionality in one place, providing an essential enhancement to your team's productivity .
eGroupWare is a tremendously configurable Open Source multi-user, web-based groupware suite. Currently available modules include: email, address book, calendar, info log (notes, to-do's, phone calls), content management, forum, bookmarks and of course a wiki. (A wiki is an editable web site allowing members to edit, create and publish an unlimited stream of web pages on the fly - it's a great way to create an organizational or instructional manual online, or to allow a distributed team to collaborate on a single document).
