We have made an exciting addition to the functionality of Volaby Rosters to make better use of the minimum and maximum constraints for sessions. This will be especially helpful to people that use Managed Rosters.
Essentially it is going to allow your maximums to be enforced when creating rosters so that you don't place more people on that you need to. Please note that while it is going to warn you that you have reached your maximum number of volunteers on a session, it is not going to stop you from adding them if you wish. Check out the video below for more information:
You can set your minimum and maximum volunteers for each session when you are creating an activity. See more information here.
