Yep. I agree. Most recent should be at the top, even if you log off. Just because you sent someone a pm after someone else, doesn't mean they should be at bottom. You might talk to the second person more, so they should be at top. Or people should be ordered from who sent you the most recent pm, to who sent you least recent. This would solve the problem of not knowing who sent you a pm if you crash before you can check it.
