I've found that your PM's may not send out if your sent box is 100%. So everyone needs to keep an eye on their sentbox to make sure it's not at 100%, otherwise your messages will stick in your outbox and not go anywhere. Thanks
Sean,
Well, I have waited all day for two PM's to leave my out box and they are still there. I only have 20% full mail box. Something is going on weird. I would have submitted by PM but you would have not gotten it.
Here is something nutty! My sentbox was 100% full, but I know for a fact that I have sent several PMs already today... strange! I just emptied it to be safe.
Apparently messages will stay in your outbox only as an indicator that they have not been read by the recipient. Once the recipient reads your message it clears from the outbox. Pretty cool as it indicates that your message has been read or not...
