FAQ - What is the difference between "Slots Volunteered" vs. "Unique Volunteers?"
Unique Volunteers shows you the number of individual people that have volunteered. Some may have volunteered for more than one slot.
Slots Volunteered shows you the number of volunteer opportunities or volunteer slots that have been filled. For example, 26 people have signed up for a total of 63 volunteer opportunity slots.
If you have a "Volunteer Opportunities" Form that has 75 "slots" or "opportunities, and "Slots Volunteered" says 65 - that means 65 of the 75 slots have been filled (even if they are filled by the same person more than once.) If the "Unique Volunteers" for this same form says 27 - that means 27 individual or "unique" people have signed up on the form.
