Have you thought of teaching a course on Construct 3 for Udemy or Skillshare? I think you'd do really well there.
Not really a way back i wanted to open a youtube tutorial channel but im lacking time ... have multiple projects on my hand some bigger some smaller and i do Construct tutorials to relax, where i can share some of my experience with it.
But i did found Udemy, being very good for teaching and learning online, — Udemy and Skillshare is not a scam on that part, they can't be, there are courses for sale for those that don't want to learn things the traditional way, or don't have time. People call scams on anything today that is overpriced, and as any market there will be low quality content for 400$ from what you don't learn nothing, or a amazing course that is 20$ and you learn everything you want on the subject you pick. But that is not Udemy fault, more of the sellers fault.
— Probably in the future when i find some little time on my hands to gather the most frequent needed tutorials, il consider it either posting it on my own blog, udemy like site or youtube, but as of now chips to much time. Thanks for the appreciation, and im glad it helped you.
