Private Messaging
Location - Plug-Ins
Here we have options for viewing, replying to and deleting messages sent to a specific administrator. Choose a name from the "Select an Administrator" dropdown at the top of the page to view correspondence for that administrator. You can also choose to view either your inbox or your list of sent messages.
Under Configure for this Plug-in you will see your list of administrators and here you can also add administrators. Note that the admins setup here are not the same as site admins, these "Reply From Name" entries only apply to the messaging system and are used as aliases to hide the site manager's identity.
Members can submit messages and read replies via a site's members area.
