Abstract: A method for use in a computer simulation includes receiving a request from a first user to initiate a multi-user session, retrieving tag data for a second user, wherein the tag data includes tags entered by one or more users of a plurality of users including the first user, evaluating the tag data, matching the first user with the second user based on the result of the evaluating, and initiating the multi-user session with at least the first user and second user. Another method for use in a computer simulation includes establishing a multi-user computer simulation having an ability for one or more users in a plurality of users to enter tags for other users in the plurality of users, receiving tag data for the plurality of users, wherein the tag data includes tags that have been entered by the one or more users for the plurality of users, evaluating the tag data, and matching a first user in the plurality of users with one or more other users of the plurality of users based on a result of the evaluating.
