What other reason would the letter "i" be used alone if not to be referring to yourself in the first person?

Ha ha, I know the feeling! In Word you can set up automatic changes for words you regularly misspell, which feels like it’s reading your mind, if that helps at all?!

I’m not very tech smart so what is Word? I have Microsoft Windows XP.

Ah, Word is a word processing programme, usually available on Windows but it probably doesn’t come as standard – which programme are you using where you use spell check?

Firefox, Chrome and Safari have spell-check as part of the operating systems. You might want to switch to one of them.

I am using Firefox and spell check works sterling except the “i” word. I have to go back and upper case it manually.

On the Apple products, it auto-corrects.

I don’t think Firefox checks for capitalization, only misspellings.

@Aethelflaed is correct. Spell-checkers only check spelling, not capitalisation. However in Word and Open Office (and presumably most other word-proessors) you can use Auto-correct to fix this error.

Imaginary numbers.

Firefox will correct caps on some words, like germany. It gives the red wavy underline and will capitalize the G for me-Germany. That’s why It seems to me that “i” by itself would beg to be corrected in the same way. Somebody get Bill Gates in here NOW!

Points in a list, similar to Roman numerals except they’re lower case.
