Put an underscore on either side of the word, like this _myunderlinedword .Andy said:Surround it with _underscores_ instead of *asterisks*, you won't see it
as you compose the message, but many newsreaders will show it when
displaying the message. You can also use /slashes/ for italic.
You need one right after the "d" as well (which I can't put there right now
for obvious reasons).
Once the newsreader sees the underline character on either side of the word,
it not only underlines the word, it also thoughtlessly, leaves the underscore
characters to either side, to spoil the effect.
You can also look at Andy's post on an archive, to see how the effect is done.
