How do I post a comment on a blog? - How do I post a comment on a blog? Posting a comment on a blog is a lot like replying to a message on a board. If the blog is open for comments, you'll see a post with a comment link or a comment count link at the bottom of the article. To post your comment: Click on Comment or Leave a Comment . You can post a comment to an article or to someone else's comment. Type your comment in the comment area. You can use simple HTML and quote the article you're commenting on. Tip: Unless you have special permissions, you can't edit or delete a comment after it's posted, so be sure to preview your comment and spell check first. Click Reply . Some blogs display new comments almost immediately. Other blogs don't display new comments until the blog author or a moderator approves them.
