This roster is allocated week by week, known as "rolling allocation". See the links above for associated pages. Each volunteer in the preferences page is considered for allocation at their "Fixed Period" ahead, as indicated in the preferences page. Those who are available, do not have a clash and have more than the median interval since their last duty will be allocated if needed, and sent an email advising them of this. This allocation process respects the RosterUnavailable page, and attempts to avoid clashes with other rosters. If you are unable to do an allocated duty, you need to arrange a swap.

You can pre-empt the automatic allocation by allocating yourself to dates of your choice; simply enter your WikiName in any blank cell. Instructions here.

Automatic reminders will be issued by EMail during the week before a duty. These will obviously only be correct if swaps have been recorded here.
