Just a few things, because some other people have already said things I agree with, no point in me repeating, and as usual I'm doing many things at once...
Regarding CL inactivity, when I took over CL of vamps, I implemented the only thing I think we can currently "do" to try ensure we dont have clans without CLs. There's no set way to manage this without IMM involvement really, but the problems mainly seem to happen when CLs come back from being inactive and chucking a fit.
In Vampires, in a nutshell version, I have layed down set rules and procedures a CL should follow. If a CL becomes inactive for x amount of time, they are to be replaced, and demoted. It's effectively a contract. By taking the position of CL, you accept that if not active for longer than 4 weeks, you will be removed from CL, and the CCL, next highest member, or member voted for CL by other members (OR selected as the "next CL") will come into play.
In vampires, I have already expressed who I'd like to be CL, should I become inactive. First and second choice even. Everyone is aware of the rules.
I have also laid out "application systems" for anyone who wishes to apply for being CL, whether the current one is active or not. Many different variables come into this, and a lot of detail which I won't go into here.
Running a clan is more than just sitting around, occasionally recruiting. I think a lot of clans would run smoother if they had some procedures and policies in place. That way, if it is set in stone, and imms do end up having to follow the instructions left BY the CL in the first place, they cant get in trouble, and the "inactive" CL just needs to accept it.
Cant play, dont step up to the job.
Any of my members are welcome to apply for the CL position from me, should they desire.
And if I am not sufficiently active, I will be replaced.
Lay some rules down for your clan, people.
