GitHub: Is it possible to collaborate with someone on a private gist?

Question

I have a private gist. If I send the URL to a friend he can view it, but cannot edit it, unless he forks it.

Is there a way to edit it directly without forking it?

Answer 1

I am not sure it is possible.
To make a gist public (which is not what you want, but illustrates the lack of management features around gist), the only solution was to re-post it.

There doesn't seem to be a GUI for adding public ssh key for collaborators, like there is for a GitHub project.
