When you add an umpire, you also have the option to add a "Dummy Umpire". A dummy umpire has only a single identifying (first) name. In lists of umpires, they are listed with their identifying name followed by the last name "Dummy". For example, if the supplied identifying name is "Metro League", they will appear in the umpire list as "Metro League Dummy".

As the word implies, dummy umpires are not real people - as such, they have no log in credentials and adding one does not add an actual user to our system. Instead, they are intended as "placeholders" for umpires who, for instance, are assigned by someone outside our system. Typically the identifting name supplied might be the name of the league or organization that is actually responsible for assigning them.

Dummy umpires do have optional email addresses. If an email address is supplied for a dummy umpire, that address will receive emails if, for instance, a game is rescheduled that the dummy umpire has been assigned to. So often the email address will actually be the email address of someone who has responsibility for assigning a real umpire to a position the dummy is assigned to.

Of course, because of the intended use of these dummy umpires, we allow them to be assigned to concurrent and/or overlapping assignments with no warnings generated. Thus a single dummy umpire can be used to represent many actual umpires.
