To post a comment, click (No/1/2) comments under the blog post. You have to select a profile when commenting. If you select “Name/URL” from the dropdown options, a box will pop open where you can write your name (you don’t need a URL). Real or fake names work. Click continue and then you can write your comment and post it.
To view comments, you either need to click on that post (the book title and author name) or click the (No/1/2) comments thing. Either way will bring you to the same page. Hope this helps.
