One of the first ways I contacted my current fire department was through its Facebook page, I'm a millennial what can I say?
One of my duties after I joined was to "fix" the Facebook page which meant changing it from a facebook page setup like a person (example https://www.facebook.com/wwillowsprings.wsfd) to a facebook page setup like a organization/agency (example https://www.facebook.com/Crockerfireprotection). In my wanderings around the internet I have come across MANY fire departments that still have their pages set up like personal accounts and I wondered why, what I found out is that a lot of people don't know how to set up a facebook page and make it look official.
That's what I'm offering to do for you. If you would like a Facebook page for your fire department send me a private message on here and I can set it up for you. When its done I'll give whichever person on your department you want control of the page and that's it. This is something I'll do in my free time and it will cost you nothing.
Shoot me a PM if you're interested, stay safe.
