We also have a community FB page. Mostly updates about the park, activities, things for sale, photos, funny posts, etc. It is well moderated, so no politics, religion or nastiness allowed. Lately, it has been flooded with posts about neighbors who have been injured, sick or who have passed away.
You first need to join FB and then you just go the main page, look up your community name in the search area and it will take you there. You will probably have to sign up for that group too, with a password and/or request to be accepted to the group, as I am sure it is a private group only.
I didn't get on FB for years and finally, my friends convinced me that I had to join. I went on there kicking and screaming!
But now I spend a lot (way too much!) time on there every day. It is a good way to keep in touch with family and friends, current events, funny posts, etc. I no longer post the political stuff now, but mostly cute stories or photos of animals, funny stuff, and just keep it light and fun. There are different groups you can join as well. I am on RV, cat, otter, wildlife, gourd, CA photography, Ghost towns, etc, groups on there. There is pretty much a group (or several) on there for any interests you can think of!
I have gotten in touch with old friends I haven't seen or heard from in decades! I recently joined a group from the lake area in MN where I grew up and have seen several people on there from my old neighborhood and from school. It is fun to keep up with everything that is going on back there.
