It turns out that Sigil has tons of the features I needed to use, ages ago, including a word-count feature. They just don’t put them in the program anywhere that you’d know where to find them or what they do.
Argh argh argh.
Anyway, it would seem that Part 1 was 108,000+ words, including indexes and forematter. So that makes me feel a bit better about how long it took.
The next step is to get Part 2 out, which shouldn’t take as long because it’s practically ready. I also need to get back on the translation truck, though, because it’s been practically a year.
