Though the iOS-inspired Reminders app was a significant new feature of Mountain Lion, one of its abilities has been overlooked by most users -- a feature that lets users share reminders with other users. Until today, the feature was exclusive to Mountain Lion, and curiously absent in iOS 6. Apple has now added the shared reminders ability to the online iCloud.com version of Reminders, foreshadowing its likely addition to iOS 6 in a forthcoming update. Sharing a reminder makes it appear in the other users' Reminder app, or is sent to their email.
