What is the proper protocol for addressing one's title and position in an email signature? I am creating an email signature and I am not sure what the protocol should be.
Should it say

Dr. Locc
Department of Social and Consumer Sciences.

or should my position within the dept. be referenced??

Dr. Locc
Social and Consumers Science Department Chairman
There is no formal protocol for a "signature block." You can put as much or as little as you would ike. If you know the recipient well, for instance, the block is unnecessary. For more formal occasions, however, I would include as much of your affiliation as is appropriate:


  I. M. Professor
  My Job Title
  My Department
  My University
  Other contact information


If you are chair, I'd indicate that specifically. Instead of the second and third lines, those could be combined as:


  Chair, Department of X
