I feared you all would get the right answer.

In reviewing the draft, I changed "forums" to "fora" and said that the correct plural needed to be used (one of the drafters seemed to insist on using "fora" for the singular, adjectival form, as in "fora members," which didn't help me to think especially rationally about it all).

In thinking about it, I began to worry about where it would fall on the snoot-simple axis - and now, taking the wise counsel of the gang here, I get to reverse myself and argue for "forums."

Thanks for the input.
