Zope Group Calendar 0.3 released
The Zope Group Calendar is an effort to create an Open Source group calendar. Currently it runs on Plone, adding extra views to the CMF Calendar.
A new screen for changing permissions settings was added, the broken week/day view was fixed, and the calendar now shows all event-like objects that have a start and end attribute.
Downloads are available from the files section on the Sourceforge project page.
