Hi @John Murray, could be if the onboarding challenge is not completed  - the one which unlocks the Global Masters program. 
Maybe you could send me in DM his/her email address? I will forward an invitation by email, no additional registration will be needed.

Hi @John Murray  thank you for bringing our attention to that!
Working on a new picture right now, and will replace the current one asap :) 

Hi Developers, the roundtable recording is available here.
