it shouldnt be at the top of the list probably but how about an officers room. have it be similar to the clan message board but only clan leaders and up to 2 clan officers from a clan be able to talk in it. these people are the ones that really care about the game and could make some great ideas together. The Inconceivable Queen has mentioned a room for VIP but it doesnt include everyone, even if they have a majority of voices.
also you could have similar restrictions to what officers/leaders count as in wars so that someone doesnt just start up a clan to enter. say maybe more than 5 people in the clan/5 people above level 50 in the clan
