I've added a stylesheet (twitter.css) and update the zip file and instructions
If you are updating, download the new zip file and upload the contents to your forumroot, delete the additional.css template edit.
Open your headinclude template and find:
Code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script>
<script type="text/javascript" src="twitter/jquery.twitter.js"></script>
Below that add:
Code:
<link rel="stylesheet" href="twitter/twitter.css"/>
