One of the best mods which is necessary for post moderation. SMF is incomplete without ability to make post or topic hidden until its reviewed if content is ok for public or if link is suspicious.. Without this mod, after approving some topic/post you will always need to delete to recycle bin or to move content to hidden area, with this one all it does it making post hidden from public view. https://www.simplemachines.org/community/index.php?topic=575212.msg4070909#msg4070909 - also see this
