Consider resetting Clan Quest limits mid-week
Liek the Clan Quests.. Like that there's a per-player limit to number of quests you can take (prevents some greed aspects).
But not all clan members engage in the quests. That can leave several quests which are just unatainable becuase everyone who is interested in them has already used their 3 quest limit.
I woud propose a reset to the 3 quest limit on Friday or Saturday... allowing interested clan members to take an additional 3 quests if they are still available. By waiting until mid-week to reset them it ensures no one gets too greedy too fast :)
