I'm trying to help a friend start a book reading group site on blogger/blogspot. She is trying to add her mother as a participant, but it's requiring a google sign-in? Is there any way around this? Also, is there an easy/nice way to handle discussions without having to verify each participant. She wants people to be able to jump in, sign in, and start a discussion on a book each month, week, etc. So far, All I could think of is through comments. I know everyone here is much more familiar with these pages than I am.
