>>Ive typed the following into a document:
>>
>>"Each Mobility Group is referred to in the Service Categories table." and Word keeps putting that wavy green line under "Each Mobility Group". When I right-click on it I get "Number Agreement (consider revising)". I clicked on "Ignore once" to get rid of it but it keeps coming back. Now, as you can imagine, this has got my dander up so, just to keep it happy, I changed the "is" to "are" and it was happy. Not that I've left it like that, mind.

>What happens when you say "The staff is located in the main office" vs "The staff are located in the main office"

That's one of those grey-area, moot points, like "there are a number of students" or "there is ...". Personally, I say, if the noun introduced ia preceded by an artcle: "a", "an" or "the", and/or its singular anyway, even if a collective-like noun, and then "of" then it should be "is", as in the 2nd example. After all, we say "an army marches on ITS stomach" - not "...THEIR..." but, as I say, that's debatable.

>Do you have the Brit grammar or US grammer version <s>? Maybe the real test is if the spellchecker corrects "arse"

I've never been aware of a Britsh dictionary. I just assumed the spell checker does both. But I've just tried it with "neighbor" and it correctly transformed it to "neighbour". "Arse" is no problem. (Imagine the author of "Father Ted" having to fight the checker for Father Jack! :-)
