business licenses? meets?

While the district meet was in Milander, I know that there were quite a few meets for MSSh and for Columbus held at our pool. Where is the pool calendar to compare to school schedules? Revenues? Invoices for those. Also, if the private business is operating from our pool dont they need a business license? Or some type of oversight? And we were led to believe that the insurance they bring to the table covers their swimmers and coaches. If we do not have a team roster how do we know that all are registered and therefore insured? How many meets have been held at our pool this year? What revenues have we received from THOSE, if any? All private businesses that do business in MS are required to have a business license, no? Does MDAC have a business license to operate in MS?
