I took this class during the mini intensive weekend and found it really helpful. This was one case where I was able to immediately put to use what I'd learned. I was shocked at how many times I had dialogue tags and action beats in the same sentence. And that was just the first step!
My one suggestion for Kathy, if she decides to teach the class in a longer form, would be to let students post an unedited section from their own writing (at some specified length) and let them use their own work to see what can be tightened. I realize that wasn't practical for a weekend class, but I think cutting our own work would take it to the next level.
Great class!
