It's funny how the apostrophes get such a bum rap, though understandable given the "Let's make this sound more alien. Add z, q, x, and a bunch of random marks!" you run into now and again. But it's neat when they're put in for actual reasons, like glottal stops or omission or your punctuation marks.

(I'm a bit of a language construction dilettante, myself. Used to lurk around in rec.arts.sf.composition, which has some really interesting discussions. Even spent a while trying to learn lojban. So it's fun to read conlangs although I've never gotten very far in making my own)
