Does anyone have an active book blog on facebook?

Hey everyone!! I'm struggling. So long story short I have a personal blog on facebook. It is my book blog that I had with a friend. Well, she handled the more technical stuff and I handled the posts. She decided to step down and now I have full control but I want to make it to where anyone can post and talk about anything books. I looked through the page and tagging. It shows anyone can post but does not give the option on the page when anyone goes to do so. So I'm at a loss as to what I should do. Can anyone help me please?
