These are my settings in wordpress but I still always have to approve,how can I change this manually?
I know what you are after but... Do you not get spam? If your not getting it yet just wait awhile and it will come. You will spend more time deleting spam comments then you would be approving comments. Just a thought.
I don't see the point of removing the comment approval. Once you remove as the post above points out you will get flooded. And it's gonna be big time.
