Hi RedtailJasonK - -
The Zimbra/Timetrade integration works through Activesync and automatically connects Zimbra calendars to the TimeTrade Cloud. When this happens, TimeTrade can then be used to offer appointments as "published availability" through URL's or in e-mails. The setup of the system is end-user friendly and can work with 1 user on up to thousands. We don't have too much on our website yet but please contact me directly at
gary@timetrade.com and I'll have someone send information to you or whomever else is interested.
