I see this is a Facebook Closed Group
Anyone can find the group and see who runs it. Only members can see who's in it and what they post.
Why must you be a member of the group in order to see what's in it? Is there a reason it's a closed group?
I don't mind promoting other sites where folks share and connect but I'm not really a fan of promoting silos of information where you must register with Facebook and
join a group in order to read what others have freely shared.
Why not freely share the information with anyone who wants to view it? People freely shared the information in the first place.
