Apple has released a beta version of a tweaked the MobileMe Calendar Web app. MobileMe is the company’s US$99-per-year suite of Internet tools.
The MobileMe Calendar beta is a preview of the new Calendar web application. It sports a new web interface with calendar sharing and event invitations, as well as new features designed to make it easier to use. Features include the ability to: share calendars with family and friends (though they must be MobileMe members in the beta); publish calendars for groups or teams; and offer event invitations with RSVPs. The beta works with the calendar applications on the iPhone, iPad, iPod touch and Mac.
Please note that all changes made after joining the Calendar beta will be lost if you leave (unless you manually export your calendar before leaving). You will revert back to the calendar data that you had prior to joining the beta. Also remember: beta software is unfinished software so use with care.
