The Discussion Settings control how comments are handled on your site.
You’ll be able to determine whether comments can post automatically or if they need to be reviewed and approved before becoming visible to others. Select your settings here carefully as they will affect how your site is viewed and perceived by someone else.
You will also be able to identify words, phrases, IP addresses, email addresses, names and URLs that you want to “blacklist” from being able to make comments on your site.
In addition, you can decide how – or if – you want the commenter’s picture (avatar) to appear next to their comment.
