Abstract:

The features of time, place, speaker, and audience define the situational context of any communication--face-to-face, paper-based, or electronic. However, they are significantly altered in electronic communication. If participants in electronic communications do not recognize how these features are altered they may not be able to use their electronic mail effectively.
