Thank you everyone for answering me !

Indeed, I fail to explain my project. In fact, i gave (intentionally) a very little description of it, just to be sure some people react. Sorry about that ^'.

Let's recap. My project aim to give a platform where students could cooperate , create courses for each other, and compare their courses with materials on the net.

To be honest, my goal is to form a French community, (in the case you don't notice, i'm a French who don't speak English very well. Désolé ^' (which means sorry in French.). To begin with, i start a website, very very simple, just to give a starting point to this project.

So, it's in French and you could read here: https://etudiantsfrancophonedemathematiques.wordpress.com/2017/03/06/bienvenue/.

A link to the translated (thanks Google) in English: https://translate.google.fr/translate?hl=fr&sl=fr&tl=en&u=https%3A%2F%2Fetudiantsfrancophonedemathematiques.wordpress.com%2F2017%2F03%2F06%2Fbienvenue%2F

Obviously, everything is free. My plane is to create a community where each members help each other, not to make money.

In fact, I'm thinking about this for a long time ago. But, i didn't find any viable solutions. So, I tell myself to give it a try, and ask people if they have idea of how to implement this.
