It wouldn't be too hard to emulate the alternating colours of EZBoard, either, though some assistance from the code will be required.
Basically, add the following to the CSS section
.odd { background-color: #E6E8fA; }
.even { background-color: #ffffff; }
... and then alternate adding class="odd" and class="even" to each message's tr tag as you build the HTML. Then, too, if you do this you can probably delete the spacing table-rows.
