If you work at the fire department that you want to edit, you have opportunity to make many more edit options than community members. Community members can only suggest edits to the contact info, add a photo or logo. Fire department personnel can create an account to add volunteer recrutment info, fire equipment, firefighters and much more.
To apply to manage your fire department, scroll to the bottom of the fire department profile page, find the "Management of this profile" section and click to apply.
