You're a Bunch of Factors

I have a number of messages in my "outbox", are these messages which still need to be sent (similar to MS Outlook)? If so, how do I get these to send? Thanks Brice

If they are in your outbox the other person hasn't read them yet. Once they read the pm it will move to sent items.

Message remain in the outbox till the message recipient logs on, even if he/she does not read it,

I think thats how it works.
