It appears that Netscape DevEdge is gone. I am working to see if the Mozilla Foundation can get a license to important DevEdge content so that it remains available to the community. I suspect that the end of Netscape DevEdge before the Mozilla Foundation is authorized and set up to take over this function is a miscommunication somewhere along the line.
We do not currently have copies of the DevEdge material, nor do we yet have the right to display and maintain them. I am hopeful this will happen, and that we can get something in place quickly.
I’ll provide updates as soon as I can.
