Hi John, You're welcome, and, by the way, I do have both an auto-feeding scanner (sorry about the diagonal pages, someday maybe I'll go back and re-scan those) and a flat-bed 11x17 scanner. So if someone here needs scanning done, I'd be happy to do it, just to contribute to the database. > This may be a dumb question but I'm going to ask anyway.
