I think an in-game private message system would be really useful. And possibly to message other clans completely. I have so many friends who aren't in my clan and it would make it much easier to communicate with them. Or you could use it to to message a feeder clan instead of leaving joining then going back, or say good job to a clan you went to war with. Or message a guy you three stared like a boss to give him advice on how he can make his base better, even better messaging that townhall 10 jerk who three stared your townhall 8 base with all max troops.
