`ABSTRACT
`A system and method communicating via an Internet net(cid:173)
`work, the system including: a plurality of computers con(cid:173)
`nected to a computer system such that one of the plurality of
`computers, corresponding to a first of the user identities, and
`an other of the plurality of computers, corresponding to a
`second of the user identities, can send communications, and
`some of the communications are received in real time via the
`Internet. There can be a determination as to whether some of
