[Plugin: WordPress Popular Posts] Add class to UL using wpp_start= ?

Hello,
I’m trying to use this function to add a class to the UL that is returned from your plugin. Unfortunately, it doesn’t add the class into the code.

<?php if (function_exists("get_mostpopular")) get_mostpopular("range=weekly&order_by=views&limit=2&pages=0&stats_comments=0&wpp_start='<ul class='test'>'&wpp_end='</ul>'"); ?>

And it returns just this:

<ul>
<li>example1</li>
<li>example2</li>
</ul>

When it should return this:

<ul class='test'>
<li>example1</li>
<li>example2</li>
</ul>

Any suggestions on a fix? An easy one would be to able to pass an empty value, but unfortunately it doesn’t allow that either.

Thanks,
Drew
