Hi Graham,
I am working on getting Intel® Active Management Technology (Intel® AMT) and Intel® Setup and Configuration Software (Intel® SCS) up on support.intel.com for options to contact support. In the meantime for AMT/SCS issues that you would like to open a ticket with, you can use the Intel® vPro™ Technology option and use any of the contact methods there. Phone support will also become an available option.
