Request to become a contributor for course "Визуальный испанский"

There is a course Визуальный испанский which i started not so long ago and already noticed there a few mistakes. Its administrator and creator Nikolay_Nsk haven’t been noticed in community, so i don’t have an opportunity to contact him and report those mistakes. The only way i see to repair them now is to become a new contributor for this course.

Concerning my experience: In the recent past I was added as an additional admin for course webster 575+ that I recently finished. In this topic I was trying to kind of govern it.
