Because if i had to pay you to make a video tut... as i understand you want to do... you would not be happy
If people can make thier own using Camtasia or another program, why woul d they want to pay someone every time they wanted to make one. I personaly would just buy the program and make as many as I want. Try it though, you never know, you could become as rich as Bill Gates and stumble onto something big and everyone will copy you and have to pay you royalties to use your ideas. p.s. I get 10%.
