Contacting Friends

You know, long have I been waiting for League to create some way to send mail or contact a friend even tho they are offline. My idea is to have some sort of mailbox that people can send you mail to help organize for team ranked game play and other things that friends need to communicate. Communication between players needs to be improved. There shouldn't ONLY be a messaging system. We need to be contact our ranked team and let them know, hey in 24 hours we will be playing ranked 5v5. Just throwing out some thoughts. Anyone can throw out theirs as well!
