Corber is still under active development, and we encourage you reaching out with bugs and confusing points. There are two main support avenues:
Github Issues (link)
Please use issues to report bugs, edge cases and faulty implementations / documentation.
With the deprecation of the emberjs slack we no longer provide active support in that channel.
In the interim we have created a new slack group where support is being offered: https://corber-slack.herokuapp.com
