displaying the message on the computer if the filtering criteria is found within the profile.

18. The method of claim 17:

wherein the receiving element includes,

receiving a message including a data string filtering criteria; and

wherein the displaying element includes,

displaying the message on the computer if the data string is found within the profile

19. A method for knowledge management, comprising:

generating a message;

transmitting the message from a sending client to a set of receiving clients;

generating a profile on a receiving client computer;

scoring the message with respect to the profile ; and

displaying the message on a receiving client'"'"'s computer if the score exceeds a predetermined threshold.

20. A method for knowledge management, comprising:

generating a message including filtering criteria;

transmitting the message from a sending client to a set of receiving clients;

generating a profile on a receiving client computer; and

displaying the message on the receiving client'"'"'s computer if the filtering criteria is found within the profile.

21. The method of claim 20 wherein the generating element further comprises:

generating a message for identifying potential participants in an opinion poll.

22. The method of claim 20 wherein the generating element further comprises:

generating a message for identifying potential participants for forecasting uncertain events.

23. The method of claim 20 wherein the generating element further comprises:

generating a message for identifying potential respondents to a new employee question.

24. The method of claim 20 wherein the generating element further comprises:

generating a message for identifying medical doctors having a particular medical expertise.

25. The method of claim 20 wherein the generating element further comprises:

generating a message for identifying specialists having a particular military expertise.

26. The method of claim 20 wherein the generating element further comprises:
