This post is is for all users who were invited to test our coaching/lecturing system over the past 3 years. A very special thanks to those who have sent in feedback and suggestions, and also bugs and error messages. As of today we have decided to close the general BETA testing group and move the testing to our VIP users instead - who have had access to the system for the past year. We hope to incorporate all the great feedback send in, fix all the little niggles, and launch a full coaching system in the future.
I didn't find the right solution from the Internet.
