At the start of this tutorial I get the Login Forbidden error. Any ideas how to resolve?

I tried adding in a guest form on the homepage, just as stated in the tutorial, but get the following error in the console and no form renders. I just get a "submit" button on the screen.

This is just a question for idea.
I think that the tutorials should actually be a site like how Orion docs is setup. I am working on a pilot app for tutorials using the example-blog as a boilerplate. An example is a note sharing app i'm working on where the user can actually search notes, it too is a fork of the example blog.
Let me know your thoughts.

In your tutorial on security, you present a coffeescript example for tuning Browser Policies.
It's published here: http://orionjs.org/tutorials/securing-orion
On te second to last line

origin = "#{protocol}://#{origin}"

a variable origin is reused. But this is done in a loop! So the second iteration this will become something like https://http://*.example.com Which is wrong ofcourse...

It would be solved by changing the last 2 line with:

pattern = "#{protocol}://#{origin}"
BrowserPolicy.content.allowOriginForAll pattern

Please request for how to do things with Orion here, it could be unconventional, functional or whatever you would like. I'd love to write some tutorials for this but sort of need specific requests I think it's easier to write tutorials that way. Also if you know of any existing tutorials on other sites feel free to drop a link in here and we will add it to the repo.
