This is probably one of the biggest reasons why this method that is being requested can not work. There are currently about ten moderators on MNFF. If each of these moderators were given permission to mod any category of their choice, confusion and irritation would ensue. More than one mod may be modding a story at once. While the other may accept it, another would reject. The author would receive both a validation and a rejection letter. Now you've got another issue and you've left the author in the middle, not knowing where their story stand. This will only cause more problems. I know there have been times when I was in the queue and talking to another mod and we were looking at the same story at the same time because they had passed the 7-10 day mark. There's no way that all of the mods can go in a chatroom at the same time while moderating to make sure that more than one person doesn't look at one story. You have to remember that these mods do have a RL apart from the website and are
Having everyone mod every category would slow us down rather than speed us up. Mistakes would happen where two or more moderators handle the same chapter at the same time, sometimes mixing validation and rejection on the same fic because of differing opinions and moderating skills.
Also agreed! This also ties in with mods deleting a chapter because of what they think is OCC and another mod accepting it. The mods of these categories know the stories being submitted. They are familiar with it. If another mod simply jumped in in the middle of a WIP, they may view things differently because they were moderating it since it's start.
Different categories have different speeds because they are more specialist and require more specialist strengths from the moderators involved. It physically takes longer to check a romance fiction over it's general counterpart because different techniques are used in the writing and these techniques need refining slightly more.
