I love the way iJoomla looks, and some of the Drupal sites I've seen have been simply amazing. But both platforms were too complicated for me, and developers I spoke with wanted to charge a fortune.
For now, I have Subdreamer integrated with vB on one site (
www.DDRFitClub.com ). It works fine for that site since there won't be much content updating.
For my other sites, however, I need more content 'management' features, so I'm looking into having a bridge created between Expression Engine and vB. that would be the ideal for me.
