@rphair Can we get some more eyes on this? :)

agreed the getstarted rule isn't applicable here

@rphair We had that requirement once, but today external get-started pages are okay. The big advantage and that's why I'm personally in favour of get-started pages within the portal: is that they allow the projects to be found via the search function and can thus attract more traffic to their site. (but everyone has to decide for himself)
