V0.4

What's new in this version ?

Now you can create a post, you modify and delete it. Only if you are the creator of the post. I also add http error handling. If a post doesn't exist now a 404 error page appear. You need to be register to create a post (if not, a 500 error page will appear), but you can see the post without a registration.
