The best way to comment on Genesis is to join the Study of Genesis group and post comments in the various chapters. Tom is currently in Chapters 10 and 11, studying through the book of Genesis. To join the Genesis group, hover on "Community," then click on "Study Groups." With the list of study groups on your screen, click on "Join" to the right of "The study of Genesis." Then you will be able to add a comment in the specific chapter you want by clicking on the chapter and title, then clicking on "Add a comment."
The second option would be to place comments in the general forums, by clicking on "Biblical Studies Room," then on "Post New Forum Topic."
