Hey hey! That challenge is a bit odd due to a change in GitHubs API. The directions for that one read:
In your fork of "dojo_rules", add the user "codeschool-kiddo" as a collaborator by granting Mastering Github access. Due to a change in the GitHub collaborator process, we'll need you to use this link rather than using the "Collaborators" section on GitHub.
The link in that sentence is what you'll need to click to grant us access. I know it's a bit weird -- but GitHub used to allow us to automatically "approve" collaboration requests, but they made a change that made that not possible -- requiring this manual step.
Sorry for the frustration on this one!
