...I only get to the create your community user name and then can get no further

Welcome!

This is a user-to-user community created by Apple, but Apple does not respond here. You can ask questions and other end users with decades of Apple experience will try to help.

What do you mean by "learning centre"? I just searched Apple support and did not find anything with that name (yes, I tried both English and US versions of the spelling). Getting fast, effective help here happens when we have details. Can you expand on what you are trying to accomplish?
