Go ahead and click on the Discussion tab. This will take you to the screen that controls all the settings for your comments.

Scroll down the page and you will find settings for comments and settings for avatars and the likes.

You will notice boxes where you can block members, and boxes where you can monitor and assign your comments to either be moderated or approved right away.

Most of these settings are set to default settings for comments to appear and work. Go through these and use common sense when setting them.

When you have them all the way you want them be sure to click the "Save Changes" tab at the bottom.

Now we have our comment settings all set, lets go and see how we can turn them on and off on select pages.
