Some preview of the new Calendar UI, to provide us with feedback please use:
http://incubator.apache.org/openmeetings/mail-lists.html
The implementation will be using the SOAP/REST API, so as a bonus with the new UI we will have a complete SOAP/REST API in OpenMeetings for the Calendar / Event management and as the UI will be using REST instead of RTMP it should be easier to compile this component in OpenLaszlo to HTML5 instead of Flash.
