The list author says: "Based on active participation in the loveknowledge.org forum, you may become eligible to win one of these books on my list. How active you have to be is a judgment call only I will make but as long as you contribute regularly and with comments that are significant to the discussion, eventually you should expect to win a free book from me (you pick the book). I'll limit it to one book per month and announce on the forum who the winner is that month. Spread the word about my site and that will also improve your chances to win. My hope is simply to spread knowledge and encourage more thinking."
