Member run club with about 250 members.
When I was first a member we used to get a monthly newsletter in the post!
Then it moved to email, then a FB group was set up and the newsletter fizzled out because all the info that would have been in it had already been posted on FB.
Increasingly it seems younger/newer members don't use FB, and many people who do use it are trying to reduce their screen use and don't visit that often.
So what is the alternative? It's things like publicising events, asking for volunteers, asking for ideas/opinions.
Everything run by volunteers so ideally not too labour intensive.
