Client-server conference and user seeking is disclosed. In one embodiment, a system includes at least one server of a first type, a server of a second type, and a client. Each of the at least one server of the first type maintains at least one conference. The server of the second type stores a server list of the servers of the first type. The client queries this latter server to obtain the server list, and then is able to query each server on the list to learn of the conferences maintained by these servers. User lists may also be maintained by either the first and/or second server types, for querying by the client.
