Working taxonomy
Compare the results of these:
http://www.applefritter.com/sandbox/taxonomy/page/and/70
http://www.applefritter.com/sandbox/taxonomy/page/or/70
And then these:
http://www.applefritter.com/sandbox/taxonomy/page/or/70,68
http://www.applefritter.com/sandbox/taxonomy/page/and/70,68
That should definitely bring up the "Apple II Hardware Guide", since it's both a Guide and Hardware. I think this is a problem with my mysql query in the taxonomy module, if you have time to look at it.
This is critical to getting the display of categories working.
