Private messaging:
I propose that private messaging be added. Where the option could be added is when you click on the inbox, just have an icon there.. Reasons for this is, sometimes there is a need to tell a person in the clan a specific thing and they are not on currently, or you need to tell them something that you don't want other clan members to hear. Private messaging would help accomplsih this. Now, there can be problems with this. People could spam each other and annoy them, therefore only co leaders or the leader should be able to have this action available to them. Also, private messaging would keep people from having to give out other messaging system info to contact people, the notifications would bring attention that something important has been said and they need to hear it.

Co-leader/leader clan chat:
This would just be another tab added to the chats. Whenever someone is made co, they would automatically be added to the chat tab and whenever demoted, kicked, or they leave, they are removed. The leader would have the option to add elders to the chat as well. Reason for this would make it easier to talk about clan issues without the members getting into the conflict and making problems. I have personally had this happen and it's not fun. A leader chat would be helpful.

'Last on':
What I mean by this is just a thing that only co leaders and leaders can see. Basically tells when the person has last been on. Like a timer under the player's name when the 'view clan' button is clicked. For me, personally, it would help a lot to know how active a person is. I like an active clan and it's hard to tell when people aren't on at times. For people who don't care about being active, they could just ignore the timer or there could be an option to not show.

My comments:
With these ideas, there are some pros and cons. I mentioned some already. For me, it's something that would help me a lot as a clan leader. Not that I want to stalk anyone with any of these things because I don't. It's just helpful to know some of these things and be able to contact people when they don't pay attention to chat (private messaging).
