Anyone know a good CMS that can handle 1k+ categories and isn't a resource hog? please don't say wordpress cause it couldn't handle anything over 500 categories. Joomla is a resource hog so that can't be used.
try RapidVector www.rapidvector.com the cms system developed in .net and they are able to full fill your requirement.
Well.. depending on how you define "resource hog", Drupal 6 might work for you.. older versions of Drupal truly were hogs, but Drupal 5 is much improved, and Drupal 6 is reported to be even better.
