Bill D, I love the "Examples of Real-Life Apostrophe Abuse" page on the site you linked! *G*
Funny thing, though: In all their examples of proper apostrophe usage, they used the IMPROPER single-prime (a.k.a. foot-mark) character instead of an apostrophe!!!! Go figure.
BTW, is there a way to type an apostrophe (using Mac) so that it will show up as such, here on the Forum? Is it an HTML character?
