Module : Messages
The message center is a great way to send and recieve internal communication from within your site - whether this member to member or member to admin!
Any member that recieves an internal PM is, by default, emailed of it's reciept. But this feature can easily be turned off or on again by clicking a link in their Inbox.
The email simply informs them that they have Private Mail, and gives an overview of the message. A link to login is also supplied in the email which convieniently re-directs them to their Inbox.
Admin, Site Owners or Developers can set how long it is before the messages in the Inbox are "flushed". This keeps database memory down to a minimum!
