Thank you for your kind comments.
I would just like to add. You only need to donate once and the future updates are free for the same version. So be sure to check back from time to time for any new updates.
Not only does it function as I need it to, it's also pretty, which is a plus since I am trying to retain visual appeal on my site as well as a wealth of knowledge.
The support community is also excellent and the developer addresses concerns immediately. This is to be expected from JW, who has consistently maintained an excellent reputation as a developer.
This extension will do exactly what I need it to until Joomla 1.6 is released, which (hopefully) should have both nested categorization and a built-in CCK. I hope anyway. If not, we will still have K2!
