Can I sync the TalkingParents Calendar with an iCal or Google calendar that I already use?

No, we do not currently support this functionality.

Since we keep a record of all edits to events in the Shared Calendar, it is not currently possible to keep an accurate record if we allow members to export or import the calendar to or from other electronic calendars. TalkingParents is always looking for ways to improve, and we hope to have a solution for using other electronic calendars in the future.
