Free (Technically PWYW) GM Resource: Editing for TTRPGs

I do not consider myself an editor, even though I have some editing credits for RPG stuff and I've been our in-house editor at work on our student workbooks, which we update every year or so. Because I have some experience editing I have enough experience to step-up in a group of folks with absolutely no experience, but not enough to give any original advice.

So this week's free (or PWYW) GM Resource is some editing advice from someone with "close to twenty years I have freelanced as an editor for both speculative fiction and tabletop role-playing games."

If this advice helps even a little bit.......
