As an official, you have access to the list of officials for your site. By default, your contact information cannot be seen by other officials unless you allow it to be seen. Other officials can send you messages by logging into the site, however, if your email address is marked as "private", they will not be able to see your email address.
If you do not want other officials to see your name in the directory, or to send you messages, check the Hide Profile from Other officials checkbox. If an official is assigned to the same game as you are, they will still be able to send you a message.
