I ended up with an extra copy of Michael Adams, ed. "From Elvish to Klingon: Exploring Invented Languages". If you want it, email me privately, and I'll mail it to you; first come, first served.

I wrote a review of this that I have submitted to Mythprint. Bottom line: I liked the Portnow article and some of the appendices, I liked the Romaine article with reservations, the rest I thought less interesting.
