I know that I proposed this before and as far as I remember there was no harsh opposition, so I go again, observing the 60 day rule for active threads:
* Clan leaders should be able to switch clan members availability if those are absent witout announcing and did not switch tehmselves. (yes I know about "kicking members" but I feel that there should be another option.
* Clan leaders should have a possibility to send a reminder/question/... mail to their members. Prologuned absences could probably be cleared up using this.
