We should have Clan Alliances. Each Clan can "Alliance" with another clan. These "Regions" of clans will be able to chat with each other, and when a player moves from "Clan A" to "Clan B" in "Region A", you don't lose Co Leader, Elder, or Donations number.
If Clan A "Region A" is at war with Clan B "Region B", then Clan C "Region A" will get EXP from Clan A winning.
Also a region will have different levels. Bronze, Gold, Silver....Crystal.....
You gain Levels by having your region fight another of the same size. If "Region A" telegrams a Commander from "Region B" and he agrees, then the Clans will automatically go to war with a clan from the other region. This might be difficult to put in the game though.
Also, each region will have a leader, The Commander, and he is the leader of all the clans. He can kick promote or demote the Leaders, Co leaders, Elders etc...
The Leaders will agree which Leader will be Commander, then press a green button next to the Leaders Player Name. If that person gets like 5 green votes, he is promoted to Commander.
