Is it proper to begin a business letter with the pronoun "I"?
In the way back when, as I was learning grammar and punctuation I was taught that it was a "no-no" to begin a letter with the pronoun "I". Just trying to confirm what I think I recall as a 'rule'.
There's nothing wrong with it at all.
(As your thread is about Beginning a letter with 'I', that would have been a great title.)
