If you want to post a comment, simply click on where it says 0 comments and it will bring up the comment box. If you click the envelope, it will allow you to share the blog with friends via email. There are also icons below that where you can share on Facebook or Twitter, or Google Plus. Beneath THAT you will see boxes that you can check if you think my post is funny, interesting or cool!
OTHERWISE, if you look to the right side of the page, under the heading Blog Archive, 2011, you can link directly to the post you want to comment on. It will bring you to a page that only shows that post and then you will see the comment box right underneath the post, or if there are other comments, it will be below any other comments.
I hope that makes sense!!! :)
