5W and 1H who?
If you're just creating a document, I'd stick to either a simply formatted HTML email, or even plain text. The original Curve models came out in OS 4.2, without any HTML email formatting, and unless you are certain ALL your friends have upgraded to OS 4.5 on the Curve 8300, 8310, and 8320, some few might only ability to read pure text.
So, as in all things in life, KISS. Keep it Simple Sir. or whatever
