> Please don't use uppercase for emphasis. If you want to emphasize a word or phrase, put asterisks around it and it will get italicized.
Yes it was just one word, and probably an accident—an accident I've made myself, and felt bad about afterwards—but the guideline is specific about "word or phrase", meaning single words are included. If GGP's single word doesn't apply, what does?
Also, those guidelines were written in the 2000s in a much different context and haven’t really evolved with the times. They seem out of date today, many of us just don’t consider them that relevant.
