Abstract: In one embodiment, a request is received from a first user to create a location-triggered benefit that may be redeemed by a second user at a vendor and associated with a condition. The first user is not the vendor, and the condition may require that the second user go to a particular location. A record of the location-triggered benefit may be created in a database. Information may be received that the second user has satisfied the condition, and in response, the second user may be allowed to redeem the location-triggered benefit at the vendor.

Abstract: In one embodiment, a computer system, in response to a first user's request, creates a location-triggered gift for a second user and for a particular vendor location, determines the second user's location, and transmits information for redeeming the location-triggered gift at the particular vendor location to the second user if the second user is at the particular vendor location.

Abstract: Based on information associated with users, a social networking system recommends one or more groups for a target user to join or to create. Characteristics of the target user, characteristics of users connected to the target user, characteristics of candidate groups in the social networking system may be used to identify groups for recommendation. The social networking system may provide questions to the target user and recommend a group to the target user based on received answers to the questions. For example, the answers to the provided question identify one or more characteristics of the target user, which are used to select a group for recommendation. Additionally, the social networking system may recommend additional users for the target user to add or invite to a group based on characteristics of the target user, the additional users, and/or the group.

Abstract: In one embodiment, a geo-social networking system maintains a data store of shared space, wherein each shared space comprises one or more content objects, a location, and one or more privacy settings. The geo-social networking system allows a user read-access to a shared space based on privacy settings associated with the shared space. The geo-social networking system allows a user write-access to a shared space if the user is at the location associated with the shared space.

Abstract: In one embodiment, a computer system creates for a first user a location-triggered note specific for a second user and for a particular location, determines the second user's location, and transmits the location-triggered note to the second user if the second user is at the particular location.

Abstract: A messaging system that organizes and presents messages to users of the messaging system. The messaging system includes a mailbox module that receives messages and generates conversation threads from the messages. Messages received from different electronic message channels may be aggregated into a common conversation thread. The conversation threads are also organized in a message interface and then presented to a user of the messaging system. The messaging system may include a social networking system that stores social information about users, which can be used to organize the conversation threads. Other features include a multi mode message interface, and a method for adding contextual information to messages.

Abstract: A messaging system facilitates communication between users through various messaging channels. The messaging system supports multiple communication channels and includes a messaging module that automatically selects one or more of the messaging channels for delivering a message to a recipient of the message using, for example, a set of policy rules or a trained model. The messaging module may also provide, in a user interface for sending and receiving messages, a visual indication of the selected messaging channel to the sender of the message to provide the user with transparency about how the message will be delivered. Additionally, the message may be delivered via multiple messaging channels, where the messaging module may rescind messages from some of the messaging channels upon receiving a reply from the recipient of the message or other confirmation that the recipient has seen the message via one of the communication channels.
