One do all
One person prepares the shifts ahead. Then the publishers tell him what shifts they want and the responsible updates the schedule accordingly.
Then everybody can see which shifts are full and which ones are available.
Book shifts themselves
The responsible one prepare the shifts ahead. The the publishers log in themselves and write their names on the shifts the want to attend. The responsible one oversees it all and polishes the entries to look the same.
The publishers approved for local cart witnessing must have an account of their own (crated by Admin) and have the role Public witnessing activated.
If someone feels that it is to hard to book shifts, that person may tell the responsible one every time he och she wants to book a shift and the responsible one can help with writing the name on the right shift.
Some congregations choose to hide the button and schedule for the Public witnessing from the ones not logged in. It can be done by the Admin under Settings ().
