I like it. Good idea!
I see this message board in two ways. The first is actually not what people might expect. I see it as a place to gather and document the experiences of people going through the process — like we are building a giant HOWTO document on finding faith in the Church. The second is of course the traditional support-group social nature.
So in keeping with the idea to build a library of useful information to help people “stay lds,” a section for book (move, audio, etc.) reviews would be great.
