A number of ideas, apologies if these are repeats. Mostly clan admin
1. Longer emails for leaders. Not looking war and peace but 100 more characters would be nice.
2. Some sort of Private Chat, even just between co-leaders or elders.
3. A practice attack option between clan mates.
4. A search function for players similar to clans.
5. Extra info on storages and mines in game so players know what percentage can be looted when they are attacked. I know its available elsewhere but it's a frequent question.
6. Couple of bigger ideas - clan wars and a duel area for pvp, suggestions from clan mates I thought id add in.
7. A way for leaders to link clans so they can show a legitimate relationship, i.e, feeder, and also make it easier for players to find the other clan.
8. A bulletin board inside the clan where info could be posted rather than repeated endlessly.
