I received a couple of PM's, and I've written replies and clicked 'post'. However now the replies seem to be stuck in the outbox, and there is no evidence that they were actually sent. My "Sent Messages" box is empty. I can't find anything in the outbox that would allow me to send those messages. Anyone know what I'm doing wrong?

Until the person reads them, they stay in your outbox. Once they are read, they appear as sent.

thanks!
