Let's say that your clan consists of people from all around the world.(which most of them do) To discuss certain topics about changing policies in the clan or kicking a member who may be unloyal but may be a friend of one of the other leaders this column could create a space where to players in the clan could meet. It might be a dum idea but I would find it helpful in my clan.
In this column leaders and co leaders can discuss the right number of trophies or level needed to join/ stay in the clan. This way you do not worry members into leaving the clan before you send the clan mail. I have had past experience with this in a clan with a few of my friends and strangers where we deciding lvl 35 and up or lvl 25 and up. About 6 or 7 members left the clan before we had even decided. This column could also be used as a 'kick suggestion' column. As I have seen in past experiences with new clans, some leaders may offer co leader to the first 3-5 people who join. Starting a clan is very difficult and when a 'hopper' joins, gets co leader status, and kicks everyone out and changes the clan message it is difficult to start up again. The 'kick suggestion' would send a message to the leader or even send a donation sort of message in where leaders and even elders could vote on the decision. If you have any further questions feel free to reply
instead of another global chat, they should have a chat with the enemy clan in clan wars. Like so the two clans can chat between them and the overall war expirence would be better
