To the uninitiated to WordPress, here’s a quick guide:
1) At the bottom of each post, there is a link called “Leave a comment”
2) Click on it, and this box will pop up:
3) As it says, type in your comment in the box.
4) As you type, another box will pop up below. Type in your name and email address.
5) Finally, click on “Post comment”.
6) Easy, isn’t it? 🙂
