What is a person called who is appointed to take care of a community's daily business?

a city manager??

Mayors are usually elected, but city managers are usually appointed by the mayor and/or city council.

=)

my guess would be a mayor, but it's just a guess.

Your guess is close, but not quite accurate. A person who is appointed to take care of a community's daily business is commonly known as a City Manager. The City Manager is responsible for overseeing the administrative and operational functions of a city or municipality. They are usually appointed by the mayor and/or city council and serve as professional administrators rather than elected officials. It is worth noting that the role and title may vary depending on the specific structure and practices of a particular community or country.
