Thanks for the reply!
I'm able to find where to change formatting based on whether it is a new message or a reply, but this won't allow me to do what I need it to do. When I send the initial message I want it in regular font, when it is received it needs to still be regular font, but when I receive a reply I need the reply in regular font, but my original message italicized, and so on.
I may be overlooking the setting somewhere if it is there but I can't seem to find a way to do it.
