Onymous and Anonymous Messages

Speech communication and interpersonal communication textbooks identify lots of characteristics of verbal messages. For example, in The Interpersonal Communication Book, I identify the packaged nature of verbal messages, message meanings are in people, meanings are denotative and connotative, messages vary in abstraction, messages vary in politeness, messages can criticize and praise, and messages vary in assertiveness, and messages can confirm and disconfirm. The idea here is to explain the nature of the message system and at the same time to include some communication skills. In going through the Canadian Edition of Messages, co-authors Rena Shimoni and Dawne Clark include a short section on anonymous messages in the workplace. It got me to thinking that this is another essential characteristic of messages that needs to be covered, especially in this age of social networking.  Hence, this (still very preliminary) explanation of onymity and anonymity. Any thoughts would be appreciated.
