EGroupware is a multi-user, web-based groupware suite. Currently available modules include: email, addressbook, calendar, infolog (notes, to-do's, phone calls), content management, wiki, project management, tracker, timesheet, knowledge base, CalDAV/CardDAV
The screenshots look great!!! Too bad I can't install the software and try it out, though. The documentation, forums, comments, etc. say that the "eGroupware-egw-pear-xxx" package also needs to be installed and that the file can be found here at SourceForge (under Files). I cleaned my eyeglasses to make sure I wasn't missing something but the file still isn't there. Also, just to be sure, I had another IT professional try to find the file -- no success. Apparently I'm not the only one with this issue, so if anyone can find this elusive file then please share your discovery here or on the EGroupware Community Forum...
Strange project. A lot of bugs and a very well hidden bug tracker. Seems like the developers try to force the users to buy the commercial support. Additionally this project has a lot of bug regarding the calendar part (iCal/CalDav/GroupDav) which makes it IMHO nearly unusable.
