A blog is an online journal where people can post articles and comments. Anyone with a web browser can visit a blog, sign in with their username and password, and begin writing.
When someone posts an article on a blog, other readers can see it and read the comments. If you want to leave your own comment, you first need to log in.
If you’d like to read the latest posts without having to sign in, you can browse through the blog’s archives. All of the posts are listed in reverse chronological order, so the newest post is at the top of the list.
When you’re finished reading an article, you can click on the “post a comment” link at the end of it. This will take you to a form where you can type your name, email address, and comment.
Clicking “submit” will send your comment to the author of the article.
