Question-2: Comment Moderation Option
New Installed User. Just posted Question-1. This question is: Do you support COMMENT Moderation? I need to review and approve or reject all POSTED COMMENTS. If yes, how to I turn this on?
Please read this doc: https://wpdiscuz.com/docs/wpdiscuz-7/wordpress-settings/before-a-comment-appears/
wpDiscuz is also well integrated with Antispam plugins like Akismet. You can use it as well.
This may have been an issue on my end. I just checked my WP Settings.
Dashboard >> Settings >> Discussion
Below: Right Click view in new tab.
I'm now Checking the "Comment must be manually approved" Box and will test again. I guess I had previously approved the Author in previous test and that's why the their subsequent comments didn't require moderation.
