I'd just like to ask that everyone please turn on their private message e-mail notification.
Go to My Profile, then View/Update Profile, and where it asks "Be notified by email when someone sends you a private message?" choose yes. Choosing yes will send you an email containing all the text of the PM, saving the message for you in case the board deletes the PM.
We are aware that it is an issue, and it's frustrating to me too. This is the second time trying to post this, the board ate my first one. We are planning a message board update, but I haven't heard a specific date yet.
