I can only agree with what was written so far. It is nice that you want to help people, but please don't create video tutorials unless you're absolutely sure of what you're telling and you really add something over the existing resources (i.e. the official tutorials and documentation). Otherwise, everybody loses precious time: you as the creator of the tutorial, people watching it who don't really learn what they expect and have to re-learn things, and the forum community which has to rectify mistakes and explain the content.
Furthermore, this is a project, and as such it has been posted in the wrong forum. I don't know what people expect from posting in "General Discussions" (maybe more attention?), but I've noticed it happens more often lately. This section really concerns only discussions about SFML in general, meaning its fundamental design, its development process, and so on. Personal projects -- be it games, applications, tutorials or articles, should be part of the Projects section.
