We’ve added three example comments below this post, so you can see how comments work and are displayed, on your website.
There are various options WordPress offers on how to manage comments. The default, and probably the best option is that comments require approval (moderation) from you before they appear below your posts. You can opt to be notified (via email) when someone makes a comment, you can then either approve or delete the comment. Once approved the person commenting is automatically approved to make future comments.
