The Punctuation Game
Not sure what the title means, but this might help me with my oft-criticized apostrophe issues.
My apologies for the meaningless entries of late.
This is probably why people take the time to contact me about my grammatic failings. "They reveal that you have paid no attention to your own writing and invite the reader to respond in kind."
That's a great website, by the way. Writing, Clear and Simple is a blog with some great tips on conveying meaning clearly, and I've learned quite a bit from it in the last couple of months. (It's also where I found this punctuation game.)
