A system and method for observing the communication behavior of a user, and analyzing data regarding the user's contacts and community. An electronic message (for example, from the user to a group of contacts) is intercepted and copied; the message content and message data are stored in a database. A contact value is determined (for example, a score is computed) for each contact in the community of the user. Each contact in the community is optionally assigned a ranking. Relationship data (data regarding the user's relationships with the contact and community) is extracted from the message content and message data. Statistics are compiled relating to the user, the contact, and/or the community. A list of contacts is compiled and monitored over time, thereby providing information regarding patterns of the user's behavior.
