I have been searching but not finding any answers to my question if there is any way to build stuff with a block-like functionality in EPiServer 6 as you can in EPiServer 7. The main reason I want to do this is because I want to enable admins to set access rights to parts of pages.
Being the noob I am in EPi the only thing I've come up with is to make pages which I make Ajax calls to. Maybe someone here has a non-ajax approach that can be used?
