I have two sets of muses. The ones for my Nano and the ones for another story. I told the second lot they could have the editor for the whole month and do whatever they want to him while I played with the new muses. (Trust me Eddy has been making their lives hell for years, you should have seen the evil grins they got when I told them this *shudder*.)
But Ed is tricky and he escapes each night.
So I print off my Nano as I go and at night time I give Ed the print out and a yellow Highlighter. (Do not give him a Pen or a pencil or anything he can use to cross something out!)
He points out the mistakes, I promise to fix them at a later date, and then the old muses who hate him drag him back into the torture pit until the next night.
The new muses look on in confusion wondering what the heck is going on.
