Abstract: A system and method for facilitating an online collaborative community for individuals to meet each other, make suggestions to members in their network of other individuals as potential matches, and introduce members to each other. A number of features are provided that promote collaboration among members of the online community with regard to suggested matches of potentially compatible individuals. A first feature enables a user to initiate a multi-party discussion concerning suggested matches for particular individuals. The user has the ability to attach a profile of the suggested match to the discussion, which may be retrieved and viewed by the invited parties to the discussion. Invited parties may be non-members as well as members of the online community. A “social feed” is provided to a user to inform the user of activities happening on the site that are related to the user or any friends to whom he/she is connected.

Abstract: A system and method for facilitating an online collaborative community for individuals to meet each other with the assistance of third party intermediaries or matchmakers. The system provides the intermediaries with a variety of features to participate and collaborate in the process of identifying potentially compatible individuals and arranging for the introduction of those individuals. For example, the intermediaries can provide profile information about individual participants, search for potentially compatible individuals for others, or introduce individuals to each other. The introductions can be of individuals who are already participating or who are subsequently invited to participate. Introductions may also be anonymous.

Abstract: In a method of and apparatus for limiting program execution to only an authorized data processing system, a proprietary program, together with first and second authorization codes, is stored on a magnetic disc or other storage medium. The first and second authorization codes are read. A hardware module containing a pseudorandom number generator unique to the authorized system receives the first authorization code as a key. The resultant number generated by the number generator, which is a function of the key and particular pseudorandom generator algorithm, is compared with the second authorization code in direct or encrypted form. An execution enable signal is generated in response to a positive comparison to enable the stored program to be executed.
