So I learned a couple of things:
1. Smashwords doesn’t like smart quotes. It was easy enough to fix—deactivate smart quotes conversion, copy each version of smart quote, then find-and-replace on the version.
2. It also doesn’t like converted m-dashes. Which is truly unfortunate, given how much I like m-dashes. The fix for this was considerably pickier: because the symbol for the m-dash is “C”, I couldn’t run a find-and-replace without turning every “c” into “- – -“.
3. And it’s not a fan of the converted [small] 1/2 fraction. Not a huge problem—this was a novel, not a math test—but still.
4. If you follow the directions in the free guide, you’ll make it through the AutoVetter. Again, it didn’t catch the problems, above, but I hate to think of the problems I’d have had had I not gone by the book.
Learning curve, I guess.
Oh, and now that it’s fixed, I can recommend that you check it out on Smashwords (it’ll be a week or so before it’s available at Amazon or B&N): The Unexpected Neighbor.
