The section Teaching the possessive apostrophe 

Thanks to the editor who removed that section. I just want to put on record that I think it doesn't belong here. Perhaps there should be a separate article on the pedagogy of punctuation, which is an important but separate topic from the present one. I think this article is in pretty good condition, now. I have not seen a more thorough or more careful treatment of the apostrophe on the web. Let's keep it focused, though. –
