What are AM Applications?
These are requests submitted by champs, to assign a Waze community member who wishes to become an area manager and take an active and proactive role in maintaining specific areas of the Waze map.
Champs can get special approval to edit in locations where the user did not necessarily drive in.
Who can apply to AM Applications?
In self-managed countries, community leadership manages and approves these requests.
