User story: from Daniel Luxembourg:
In my group, we have introduced a rule to limit the number of slots you can sign up for to 1 per cooperation per week and to 3 in general per week. If the slot is still available 24 hours in advance, you can sign up for it no matter what.
It should be possible to configure such rules as group level settings.
This seems to be a much requested feature coming from other groups as well
Complexity: not easy I guess, many considerations
Outcomes (or what needs to be done to move forward): perhaps a session to discuss its implications and actually start designing/implementing it
