No problem at all. That's what I'm aiming for with my channel. Easy to understand, short and fun :)

[@adrianfels2985]

I'm very thankful you give those expressions for free to us.
But honestly, I'm sorry but I don't learn that much with these tuts. Is there any possible way to explain how such an expression works in detail?
Thanks, Adrian.
