Category Order – How to change order?

Hello,

I’m starting a new website and I’m trying to edit the category order that is in the header.. I’ve installed “My Category Order” plug in but it didn’t work for me…

So I went into the theme editor and found this..

<div id=”navigation”>
<div id=”categories”>
<div id=”catlist”>

<?php wp_list_categories(‘&title_li=’); ?>

Now, instead of listing them by title like it says, what are some other things I can put in there to list them in a specific order…

Thanks
