Control Panel Location:
Settings --> Comment Settings
This section of the Control Panel allows you to define comment settings of your site. If you are using the Multiple Site Manager, note that these settings are per-site.
When set to enable, channels will be able to use the comment module.
When set to “enable”, commenting will use the word censoring filters.
If this option is enabled, then comments will not immediately appear on the site. Instead, the comments will go into a queue and await review/moderation by an administrator.
Member Roles (such as the SuperAdmin Role by default) can be set to bypass comment moderation and have their comments posted immediately. That option can be set at
Members > Member Roles.
This is the optional number of seconds that must lapse after a comment is posted before that same user can post another comment. This setting can help reduce comment “spam”. The preference can be left blank or set to 0 (zero) if you do not want to impose a limit.
