The testing continues today with the Private Messaging (PM) feature that will be made available to all members. Members will be able to PM each other from any page within the members area, including forum posts. PM settings will allow each member to be notified of new PM's via email as well, if they'd like; users can be notified of all new PMs, new PMs only when they're offline, or not at all.
Additionally, PM's can be further secured by using an encryption word for each message; you simply enter the encryption word prior to sending the message...and make sure the other party has it or they won't be able to read your PM!
