I'm going to post a book title on the first of each month. Then, I'm going to get a copy of the book and read it. On the 28th of the month, I'm going to post a review / list of questions about the book. If you want to join the book club, all you need to do is
1) Log on and check out what book we're going to read
2) Read the book
3) Email your thoughts / responses to the questions to me at email@example.com any time before the first of the following month.
I'll post your thoughts as I get them, so that everybody in the club can read what everybody else thinks. I'm happy to take suggestions on books or formats. Just email them to me.
