If you are a new editor, start out right by getting advice from your local experts. This means starting with the area manager(s) for your editing areas. Increasingly, this information is found in the Country wiki pages, or in the [country forums]. You can also search the wiki for the name of your region, province, or state. For example, Pennsylvania lists the Area Managers for the entire country and Canada lists the area managers for the entire country.
Area managers are also listed right in the Waze Map Editor. Information on the wiki and in the forums doesn't always agree with what is on the map. It can be difficult to see the information on the map. So install either the WME toolbox or the UR Overview+ extension and turn on the "Area Manager" layer 
. If you are using UR Overview, you can see the list of area managers by selecting the URO+ tab.
If you cannot find the area manager information for your region, ask for help in Chat.
