How do I leave comments on a blog?If someone has comments enabled on his or her blog, then you can usually find a "comments" link at the end of each post, like this:
If you click this link, you will go to the comment posting page. In the upper left corner, there is an option to show or hide the original blog post that the comments relate to. The rest of the left-hand column contains any comments that have already been made. The profile photos of the comment authors may also display, depending on the blog's settings.
On the right hand side of the page is the space for you to enter your comment. Beneath that are the identity options.
