Have you ever tried clicking the blue edit button in the upper
right side of the screen? It gives you a plain text representation
of the worksheet. You can enter arbitrary HTML between the
cells (the {{{ }}}), and it appears looking more professional
when you click the "Save and Use" button. In fact, internally
all the text between subsequent {{{ }}} compute cells *is*
a TextCell. There is also one bonus -- if you put math in $'s or
$$'s, it will get typeset as mathematics.
