P.S. – Would using something like this plugin work for creating the Custom Post Type needed for BuddyBlog?:

Or do I need to only do it by the method you demonstrated?
Brajesh – Thanks so much for your helpful reply!!
It sounds like the first approach is probably best, so I will attempt that. I can still follow the instructions from that first blog post, yes? (Or has it changed?)
