Your macro does a thing that reminds me of a tangential questions, which is why so many people idon’t/i use styles in Word. For all the yacky-yack about CSS in HTML, you’d think people would be a lot hipper to the virtues of a style sheet in Word.
Given the way we work around here, a conversion from WordML/.doc format to HTML is no good unless it preserves (references to) our styles. As it happens, Word’s conversion chooses to apply local formatting to certain converions (w/in tables, if I remember correctly), making our styles useless.
