Yes. Here is the example in action. I'm also going to add a keywords to the products entry, and add another database table to act as an explanitory page...much like a Wiki. Also, I'm probably going to replace the Related items once I do that, so it will automatically generate the related items (based on an exact or near exact match of *all* the keywords defined.)
Ah My Goddess(Thanks, I'm glad you like my little modifications. I can give you the code if you'd like)
Update: My coding is now finished! I now have keywords for the categories, and products, and I've also added a wiki page for each keyword, and finally, I added a link to an existing media gallery, downloads, and message board discussions.
