Comments Box On Linen Theme

New to WordPress, so apologies if this is a basic question. I have created a WordPress blog for a client: http://alchemycompliance.wordpress.com/. On the Posts page it is not obvious how to make a comment. We have now discovered you have to click on the post title to open the article and then the comment box appears. However, it is not obvious that you need to do this. Is it possible to get the Comment box on the main Posts page or to add some text somewhere which explains that you need to click on the Post title. Thanks for any help! Dave
