An invitation is created on a social network. To create the invitation, a computer receives, from a social networking program operating on a first computer system by an event program operating on a second computer system, data from a social networking post. The computer identifies, by the event program, information from the data associated with a first member of a social network. The computer determines whether the information includes information about a future event that the first member intends to participate in. The computer generates an invitation to a second member of the social network for the future event based on the information about the future event. The computer transmits the invitation for the social networking post for sending by the social networking program to a user device of the second member of the social network.
