You just need to be careful on this one how you set up the
textarea... if the textarea wraps the text automatically
the browser doesn't necessarily insert linebreaks for you.
So your users may type in an entire story with absolutely
no linebreaks, and the <pre> tags will force it all
on one line. In this case it's best to turn wrapping off
in the textarea, so the output will be a faithful reproduction
of what the user typed.
