I've been playing around with this tutorial. It teaches you how to build a web app where people can find and post jobs using Symfony.
Symfony has two tutorials to make completely functional apps from scratch (and their online demos): Jobeet and Askeet.
I wonder if there are the same kind of tutorials for CakePHP and CodeIgniter?
By the way, what do you think about Symfony in comparison to CI and Cake? (which one stress people the less?)
