As of August 2007, OverSky is now free. It turns out developing is more fun than selling!
Go ahead and sign up for the "free trial" — your trial will not expire. You can certainly email info@overskyonline.com if you notice wording on the website or in the signup process dating back to ye olden days of the "30 day trial", or if you have any support issues with the calendar.
Signing up for the free trial will automatically start you off with three licenses (schedules). If you will be scheduling more than three people, rooms or resources, please email us to discuss extending your license.
