tomd, there is a reason for kamikaze pilots to wear helmets, but I won't bore everyone with it here.
Marsh, you have to use HTML codes. to get
bold, use the code < b > without the spaces inside the angled brackets, then close bold with < /b >.
Italics requires < i > and < /i >, and
underline < u > and < /u >, all without the spaces inside the brackets. To force a fresh line use the "break" code < br >.
There's a whole lot more to HTML.
