What won't I do?

There are a few things I won't do or can't guarantee doing.

I won't disclose to anyone your name or content.
I don't check the accuracy of facts, formulas, or citations (though I catch a lot).
I won't work with paper copies.
I'm not comfortable editing in languages other than English, though I edit English translations from other languages.
I won't generate much new text as part of an editing job.
I won't guarantee perfect proofreading (though I'm pretty good at it).
