A system of quota-cancel tasking/messaging

摘要

A system and method of messaging using a messaging interface on one or more computer devices, wherein an invitation for a group activity with a defined quota is sent to a set of recipients, one or more confirmation or rejection messages are received from the recipients, and outstanding invitations are automatically cancelled or rescinded when the participant quota is met, i.e. when the number of confirmation messages received is equal to the predefined number of participants for the activity. The invitation message may be sent to more than one group of recipients. The recipients may be determined by associated pre-defined conditions, such as common interests, relationships, or location, and the details about the recipients is held in a database. The invitation message may be in the form of an email, an SMS, MMS, or instant message, for example. The computer device may be a mobile phone, tablet, or laptop, for example.
