I just would hate to see the answer list filled with nearly exact words save for the omission of a final "g": nothing, nothin'; castrating, castratin' -- I'm sure you all get the picture.
I think the issue here is not the omission of the final "g", but that the meaning and the spelling of the two words is entirely different. One refers to a storm and the other refers to a place (with a capital L). In the examples you gave, Fran, the words all had the same meaning, so you could extend that rule to words that are both past and present tense such as query and queried.
Nothing like a little high drama at the "ABC's of BBM".
I will change it, (even though I disagree) if that is the consensus.
