[EX Q]: If you REALLY want to write correct, you won't write "correctly." Yes, it's in common use but it is, by the rules of grammar, incorrect. It's an overcorrection, an unnecessary addition. Here's a simple rule of thumb: Substitute the word "fast" where you're thinking of adding an -ly. Would you say "How to Speak and Write Fastly?" No. Same part of speech, but it somehow escaped that stupid -ly trap.
[EX A]:
Negative
