Which of the following would you call a school club? Writer's Workshop Writers' Workshop Writers Workshop My problem is that based on a google search, it seems to be done in all three ways. In addition, I can't change the initials "ww," because a logo has already been made, and the club website is already up. What absolutely confounds me is that in America (I live in America), it looks like the majority use "apostrophe+s," while almost everyone everywhere else uses "s+apostrophe." But the most famous American writing workshop, the Iowa Writers' Workshop, uses the "s+apostrophe" rule. But at the same time, the Iowa Writers' Workshop was created a very long time ago, and American grammar rules could have changed since that time. Help?
