A little help needed.
I have a rowdy user, who I just demoted to TL1 so all their comments will go to review no matter the category. Then I realized I’m not sure that’s going to do what i want. I searched on Trust Level, but I’m not seeing mention of required review.
Perhaps this is something better covered by a group?
Is the trust level 0 or tl1 group added to your approve unless allowed groups site setting? Then those posts will be automatically approved, and will not appear in the review queue.
I’m not an admin so I don’t have access to those setting, nor can I see how they are set.
I resolved the immediate problem by Silencing the user. I’ll can run a test with my second account and figure it out the hard way.
Glad you found a solution for now
