It would be nice if the e-mails you get notifying you that you got a private message could include the full text of the message, if not all the time, then at least when one's PM box is full. It seems that since MacNN sends out an e-mail anyway to let you know that you didn't get someone's message, it could at least let you know what the person was trying to say instead of basically just going BAHLEETED!
Just a suggestion...
