If this forum is like most others, if a message is in the outbox, it means the party it was sent to hasn't opened it yet. Once the receiving party opens it, the message is moved from "outbox" to "sent".
I myself was unwillingly offline from mi-august of 2011 to getting it back in the beginning of july this year. Now you are here again, that's what is important. Oh, carsontech is right, it means your PM hasn't been read yet.
So, since I wasn't here when you joined up- welcome to the Forum! :mrgreen:
