Here's the goal: I want a blog whose readership I can restrict to immediate family members. Others cannot even sign in, but family members can read and post comments.
I'm not sure how to do this. I created the blog and made it "private." I don't quite understand how to add people to the list. There's a place for "names." Does this presume that the people have a WordPress blog? (I'm the only family member with a WordPress blog.) And what is the difference in the types of participation? In particular, what is the difference between "author" and "contributor"?
I somehow had the idea that people could sign in to the blog with a username and password, but it doesn't seem to work that way.
The blog I need help with is leisureguy2.wordpress.com.
