The Event App is based on the Power Calendar but adds a twist. For each event, a new topic is created to track and document the event.
Credit: The Event App is leveraged from an app written by Peter Thoeny. The TWiki version is very close to Peter's work. The Foswiki version has been modified due to differences in the wiki base feature set.
Due to the differences in the app UIs, the Calendar links below go to the app running under the relevant wiki engine.
