QUESTION #2:
Can anyone post content on the wall that is a member of the group? It seems yes! It also seems that the only content on the wall that is shown is SD content from the members and not the content from the member's walls like happens in the personal fb accounts? Can you make your personal account the same way? And if you do I guess the downside is you don't see what is happening in your friends lives...
Have I got a handle on this or am I missing something? Thank you! (Still REALLY trying to figure out how FB works!)
Yes, anyone signed up with the Group can post on the Groups Wall. Depending on your Privacy Settings, others may be able to post as well.
Someone with more experience can correct me, but I think you're confusing the Wall with the News Feed.
My personal Wall has only my own content, or what someone places on my wall directly. The News Feed is a running list of what you and all your Friends have been posting, wherever they are posting it. Privacy Settings that each individual sets up will either allow or limit who sees what in the News Feed. Personally, I only let Friends see my Wall postings & personal info, but I let Friends of Friends see my photos.
I do not know if your Group has News Feed capabilities,,,,,,, but those of us who are signed up as part of your Group get everything you post on the Group's Wall showing up on our News Feed.
