You ain't missin' nothin'. The educated of the less educated would read fora as a type of flora. The educated of the less educated wouldna thin' to make the quantum leap from fora to forum.

And the less educated of the less educated ain't ever gonna use fora as the plural of forum. It ain't gonna happen. So, by using forums, you just avoid all the rule memorization that occurs in some school rooms where the kids think the rule is stupid in the first place and will go out into the real less educated than educated world and say "forums" anyway. So why fight it? I would feel like a great big jackass, to tell you the truth, referring to the "fora" I read on AWAD. Conversely, I only feel like a little jackass referring to the forums I read on AWAD since none of my friends can understand why I'm interested in posting on a word board in the first place.

Best regards,
