Hello, there is an awesome category grid plugin, which I have been using before on a single wp install. It gives a sort of portfolio idea, with a pop up and shows whatever you put in the post including the html. Now wordpress tells that its compatible up to 3.4.1, however I have had a problem that it couldnt find the images to show in the grid. Could you take a look at this one? http://wordpress.org/extend/plugins/category-grid-view-gallery/ I think it would be a good extension together with user access manager, but I dont know enough of coding to make that work (http://wordpress.org/extend/plugins/user-access-manager).
