I have searched the forum and the PHP documentation to try to figure out where the setting is to control Private Messaging.  All I can find in the documentation is this:

"Enable private messaging between members, including thread-like discussions and message history with links and attachments. Do mass-messaging or limit messages to targeted recipients with community notifications and via email."

But nowhere does it tell you how to do this.  I can not seem to PM anyone on my site (www.bourbonstation.net) and I want to activate this feature.

Can anyone help?
