Thanks.
I went to try and send it again, hoping that they had seen the message I left on their BB, and apparently it doesn't get saved anywhere either, not that I could see. That kinda stinks. You would think there should be an "Unsent" folder for when this happens.
I have a question - if I send a PM to someone who's Inbox is full, do I get notified that their box is full? I mean, is there any way to know if a PM actually made it into their box or if it bounced? I'm not concerned about people not replying because we're all busy and it's never anything earthshaking. But if I'm replying to a PM they have sent me, I would hate to think they never knew I replied. (Does that make any sense?)
