Wouldn't it be great if clan leaders could set a flag in their clan home page to indicate a default no-move time where a clan member then becomes unavailable for challenges (i.e. turns grey)?

I.e. I set 14 days, after 14 days of no moving by a player, no clan challenges can be made containing that player.

At present I am declining or amending challenges as one of my players has not moved for ages. I don't want to kick them from the clan. It would be easy to accept a challenge without realising the player is not moving, so that awards 2 of the available points to the other clan straight away.

I appreciate this would be complex where a player is in more than one clan.
