Abstract: A souvenir is provided to enable participants in a real-time sharing session to retain access to the shared content and experiences when the real-time sharing is completed in a fully actionable manner in which all of the functionality and interactivity of the content and experiences are maintained as when they were originally shared. Each of the sharing participants can get a souvenir that can be used to initiate access to the shared content such as a photo or replay an experience such as a telling of a bedtime story. In cases where user generated content (UGC) such as mark-ups, annotations, commentary, content links, highlights, animations, graphics, drawings, directions, points-of-interest, etc., were part of the real-time sharing session—for example, an annotated webpage, a marked-up map, voice commentary over a video recording of a live event, etc.—such UGC can be maintained as part of the post-sharing actionable souvenir experience too.

Abstract: Disclosed herein are technologies that allow users to create, issue, accept and participate in gaming challenges. A gaming challenge involves participants playing a gaming application to improve their rank on a leaderboard associated with the application until challenge conditions are met or the challenge expires. Challenges can be time-based, objective-based, a tournament or of other type. A challenger can create a challenge by specifying a gaming application to be played, the leaderboard to be used in the challenge, challenge type, challenge duration, and additional challenge criteria. A gaming service can maintain the leaderboard and pass challenge-related notifications between participants. Participants' computing devices can send notices indicating when a challenge has been met or when a participant's relative ranking has changed.
