matteocontrini If you think anyone should be able to deploy a forum [...] that should be actually avoided.
IMO forums should be available to anyone, not just sysadmins. Why shouldn't we work towards this goal? Otherwise, the online discussion space is lost to Facebook, Reddit and Twitter who managed to make it available to anyone already.
Edit: Which isn't to say that we should build shared hosting installers. If Flarum aspires availability to everyone, perhaps setting up a free Flarum SaaS is the way to go ?
However, my opinion is not very relevant. The project owners should define such meta goals to focus development efforts.
