Feedback:User/Bacalao/Communication

I don't know how much maintenance and manpower this would add, but in Guild Wars 2 a kind of instant messaging system would help. For example, you can leave messages in something other than just private message or guild announcement. A place they can be saved even if the player is logged off. My second suggestion is about friending. If you and another player are mutually friends, you should be able to view information such as the last time that person has logged on or off and things of that nature. It would help communication especially for out-of-game trading, such as auctions. And have options such as whether or not you will accept PMs from strangers or only friends.
