摘要

A system and method of messaging among one or more users of one or more computing devices is provided. An invitation message is being sent from a server to a first set of recipients, upon receiving such request from a sender of the invitation message, the invitation message is for participating in a group task and is associated with a pre-defined quota, the pre-defined quota being a maximum number of participants required for the group task. Then, one or more confirmation and rejection messages are received from the first set of recipients by the server, and one or more outstanding invitation messages present in one or more accounts of the first set of recipients are automatically cancelled by the server, when a number of confirmation messages received from the first set of recipients, is equal to the pre-defined quota.
