Does online training for Natural programming exist?

Our programmers were seeking online training for Natural programming. Long ago we had the application called Elite. Is there anything available on the internet or elsewhere to learn Natural?

We dont have basic Natural trainings online, but provide in the community many tutorials that
show step by step, how easy it is to create a Natural program. Also tutorials for special
topics like Ajax Web programming are available. Please check especially the “How to …” tutorials
under “Tutorials” here on the community pages.
