Can not find Wind Lake or other Mailing Municipalities

I want to search for listings in Wind Lake in FlexMLS, but it is not listed as one of the municipalities, why?

Wind Lake is not a taxing municipality; it is a mailing or postal municipality so it does not exist as an option for municipalities on the Main tab. In FlexMLS you have to use the taxing municipality when entering and searching for listings and not the mailing. For Wind Lake properties you would use municipality of Norway.

You can also try using the Postal Municipality field on the Address\School tab; however if the agent did not select that municipality when they entered in the listing you will miss out on properties.
