We have to decide which should be the content of these pages. The idea is to have these pages as static and blocked. We have to figure out what we want to write in these pages and translate it in other languages (Mandatory for 1.0: eng & ita) . "Collaborate" page can be simply a link to the guide (eg. click on "Collaborate"--> "Hey, would you like to collaborate with us? Here what you can do" and the guide, or something like this)
