With perforce, a user can get email notifications of changes to a particular file or directory by specifying it in the Reviews
field of the user record (more details in the Perforce documentation).
However, I would like to have email notifications sent to a team mailing list, which is of course not a perforce user. One kludgy way of accomplishing this would be to have a team member put the mailing list in for his email address, while another would be to create a user account for the mailing list (would this require another license?). Surely there has to be better way, though.
