I have an old outdated site that I have no intention of updating...too many customizations. Lately I have been getting hit with spam in the form of anonymous replies to blog posts. Does anyone know how to to set the permissions so that all comments and replies need to have admin approval?
thanks, I found that piece of code in the config and it was already set as you suggested "1". So they are registered users. I will try the captcha but might be interested in disabling comments all together, if possible.
