CE 7.1: Any tutorials usable for non-customers?

Hello,

I have installed CE 7.1 EhP1, mostly to familiarize myself with SAP products and to broaden my horizon as a developer. While the download and install of the software seems to be free for anybody who registers with SDN I was a little disappointed when all the tutorials start with "You need access to IDES" or "Go to the SAP Marketplace and download this additional thing to get started. Have your S-User handy". Are there any tutorials that are freely accessible to SDN subscribers who are not SAP customers or employees (yet)?

Thanks,

Tilo Christ
