Clan info board or Clan news section
As a leader I find it difficult to reach everyone in my clan with one message due to the time zone differences. Clan mail is nice but has a limited amount of info that can be stated. Kingdoms of Camelot has an Alliance wall where quality information can be displayed to help all members and all new members. I.e helpful attack strategy/base layout/clan war links, or just simple information so that when they log in any updates alerts them to view the "Clan News", "Clan Board" "Clan Notes" or whatever Supercell would like to call it. Having a feature like this would help clan leaders better help their members learn and grown as a cohesive unit and reduce the amount of repetitious chat messages/clan mails that have to be sent out so all see them.
