Abstract: Systems and methods are disclosed enabling users to post searchable data, such as information about themselves and others as well as details of a personal encounter such as the date, time and place where it occurred, to a user interface in a computer network. Search and match quality tools generate possible encounter matches based on comparisons of the information posted by a first and second user and provide potential matches ranked by quality of the match. Accordingly, the system and methods provide a place where people can post information about previous encounters (or proposed future encounters), lost contacts, and the like and to contact the potential encounter subject. This Abstract is provided for the sole purpose of allowing a reader to quickly ascertain the subject matter of the disclosure contained herein and should not be used to interpret or to limit the scope or meaning of the claims.
