How to qualify/register for 1 year developer subscription?

Hi
We already had a 1 year developer subscription which is now finished. I now tried to register for another year using the following link.
https://www.suse.com/subscriptions/developer/
But unfortunately there is no possibility to register or qualify for this developer program. All links point to the normal download pages where you can get a evaluation code for 60 days.
Does anybody know how I can register for the 1 year developer program?
Thanks,
