Not sure if it's only I who have the problem, but when I send a PM it's not saved in my "Sent messages" folder. Kinda sucks since I use it a lot when I'm playing Assassin games
There is a button to hit on the bottom (each time you send a message) to put it in your sent messages section, however there is a need for a permeant solution so that we don't have to always hit the button.
