The dropdown is a dropdown list box containing a collection of comic-related tutorials on the web, with the idea for people to be able to browse through the list as they would a bookshelf labelled "Making Comics" at their local library. It's not just so people can find things they want, but also so they can find things they didn't know they wanted.
In return, you need to put the dropdown code on the webpage for each tutorial (anywhere visible is fine). If you have more than one tutorial, you need to put the dropdown on the webpage for each. Once again, it's something that facilitates browsing.
The dropdown code is pretty simple. Just copy and paste the following HTML code...
<script language="javascript" src="http://www.between-worlds.com/tutorials/comic_tutorials.js"></script>
And it should appear like this.
