Thanks for the quick response.
The key difference between “at least 1” and setting a larger number of slots to a task, is that having “at least 1” with one signup means that the task is filled. For example, we need at least one person to sign up for cleaning, but we’d like to allow additional signups if more people can help. If we just have extra slots to sign up, it gives the appearance that the task is not actually filled.
I will look into the documentation more on the admin live search & assignment.
Thanks!
