I realize the complete interface structure, or layer in which we deal with object's we use to build portal's has changed quite a bit in DNP from 1.5 but the modular structure, design from a "point and click" drag and drop" from a browser's perspective, for content sections, modules, forums, ect, or can't forget, 3rd party modules... what I miss about the DNN/DNP days.
It's the ease of use i'd like to offer to clients, with interfaces that offer the flexibility of content management, custom forms, maybe site stats with a link, email/CRM features, ect... is what they are looking for, all with in a drag and drop "secured" dashboard!. DNN has evolved quite a bit just as DNP has. I'd just love to see the combination of these two platform's again. I truly would. o how sweet it could be.
or better yet... DNN compatible.. 
or something like it...lol
or maybe just a DNN connector module. Hey how about content,users,ect into and out of DNN. Does anyone have any experience with combining the two?
