Cool. I read this thread, and then looked at Stealth's ignored posts, and the thread suddenly got 90% dumber. You really should try ignore-listing him, even with the stupid notifications there it improves the quality of the forum so much.
I should point out, though, that Latin's a thoroughly dead language, too, and yet we have a pretty clear idea of how it's spoken, because even though it's dead people have kept reading it and speaking it in order to access information that was written in the language- and since this has been going on constantly since the days when everybody actually used it conversationally, the verbal part has stayed, too. Same with most "dead" languages- the only thing that can make the spoken form of a language completely lost is to basically wipe out the civilization wholesale, and take basically everyone who spoke the language with it (like the Incas, Cretans, etc.).
