this is an old, old thread, just discovered it. But as a former Latin scholar I wanted to address Steven's discrepancy between the pronunciation of the "i" ending.

I was taught that in the scholarly latin "i" is pronounced "ee" and in the Church latin it is pronounced "aye". Foots with what I've heard in most latin masses as well. . . and what I experienced in my Jesuit HS classes.

Incidentally, pretentious or not, I use "fora," it's simpler to explain to someone who doesn't know latin than using "forums," and having to answer to fellow latin scholars.
