Hi friends, I own teachavenue.com you might want to visit the site and register and become an instructor and create an online course to share the world whatever you are good at.
I'm inviting University Professors and teachers to create an online course and published subject you teach in school. In that manner you do not have to worry about giving special tutorials all the time. All you need to do is invite your student to enroll in your online course. You may offer it for free or for a minimal fee, your call.
Teachavenue is an online learning marketplace for people who wants to share whatever they are very good at and for students who wants to learn whatever they want to learn.
If you are a Youtuber and want to offer your course for free. Just make the videos in Public but if you want to offer a Paid course, just make it "Unlisted" on youtube.
