Abstract: A method and apparatus for automatically grouping parents, especially for parents of school-going children, who have been connected to one another in a randomly formed networking database. Each parent-user has provided information about themselves (ethnicity, religion, occupation, education, hobbies, interests etc.) and their children (school, hobbies, interests etc.), which is stored as a unique record in the database. A deterministic software algorithm uses parent records to form groups of parents. The algorithm automatically groups parents in a manner that creates an affinity between them (for example, based on the real world school relationships between their children, based on membership in a soccer club, mother's club, scout groups etc.). Once the groups are formed parent-users can filter incentives-based member-generated content using the grouping system.
