I have a private blog and right now I have only very close family & friends as members. I am thinking about extending it to other friends, but I have some content that I want only my original readers to have access to. So, I would like to have two groups, but I'm wondering what will happen when the groups get notice of new posts. If I post something that only the first group has access to, will the other group get a notice and then they can't view the post? This is what I don't want to happen. Thanks.
