I think a good feature to add to the PM system would be some sort of status report. Something that would let us know if the other member recieved the PM or not. Recently I sent out a few PM's all within a matter of seconds of each other and my computer crashed and was very curious as to if they went through or not. Just thought it would be a nice feature, like AOL email they tell you if it's been recieved and opened, unopened, or deleted.
