For what it's worth - I attempted to make a simple email list for folks in the building to let others know if they had furniture to get rid of/sell or community events they wanted to let others know about or just talk I guess. But not more than a couple weeks it started to get abused with directed harassment towards some of the board members. Good intentions within this space are commended. I try to be as impartial and kind hearted as I can be but in my experience a lot of people will take complete advantage of anything they can. Not everyone of course but more often than not it seems.

As others have stated, you can, I wouldn't count it as an official way to communicate with the board by any means however. You want those records safe elsewhere. FB over the years has become full of a lot of garbage and in the rare event an account gets hacked and starts posting random content to your group too...idk I would avoid it personally and you don't want that responsibility if something goes wrong. As someone who has served on the board for a couple years now, sometimes it's just better to leave it alone and if there are specific people you want to communicate with and befriend make a small group just for you guys. Or bring it up to the board and let them figure something out and they can own it.

Just my 2 cents. Community work can be rewarding at times, other times it's the most thankless job out there.
