Note to non-native speakers of English: Years ago, i got stuck in my brain the idea that there's something wrong about modern English singling out the first-person singular pronoun to be spelled with a capital letter. So i spell it without the capital -- except at the beginning of a sentence, or when i'm not the sole author. If you follow my example, native speakers will just figure you're just ignorant of the basics. (Otherwise, since i'm pretty careful in writing, i'm probably a relatively good example.)
