Abstract: Third-party systems outside of a social networking system allow a user of the third-party systems that is also a user of the social networking system to perform an action on the third-party system that are communicated to the social-networking system. Additional actions on the third-party system may be associated with the action. These additional actions are communicated to the social networking system, which identifies the action from the third-party system and associates the additional actions with the identified action. The social networking system may notify the user that performed the action of the additional actions. Also, the social networking system may notify additional social networking system users of the action and of additional actions on the third-party system associated with the action.

Abstract: A social networking system facilitates a user's creation of a group of other users from among the user's connections in the user's social network. The created groups may be used, for example, to publish information to certain user-defined groups or to define privacy settings or other access rights to the user's content according to such user-defined groups. When a user adds connections to a group, the social networking system determines a characteristic associated with the group and identifies whether the characteristic is specified in user profiles of the added connections. If the user profiles lack the characteristic, the social networking system suggests to the connections to update their user profiles with the characteristic.
