I think you two have covered all the bases. I have received very good concrit and very bad flames, so I understand the necessity for this sort of thing. I really like the idea of giving specific examples when possible. I know that when I am typing i have a tendancy to mangle words, because my fingers don't like following the whim of my brain at the time. So that sort of thing is very helpful to me.
Anyway, I think this is a great idea. Thanks for thinking of it.
