Why not adding a sandbox feature, where new individual contributors can try out some of the debategraph functionality, without having to fear that you are interfering or disrupting an existing debate.

A Sandbox should or could be:

2. limited in lifetime, in the sense that it would only exist for a single session. After logout or a timeout, the sandbox would be freed up again.
