Approved Topic Versions

I'm looking for a way to implement the following senairo:

A topic can have Topic Maintainers (user and or group). A Topic Maintainer can approve a Topic Version. Any authenticated User can still change the topic, and his changes are visible right away, but in the view there is a warning, that the current Version of the Topic is not yet checked and a link to the last approved version. A Topic Maintainer can then "approve" the current Version (or make Changes). The Warning would disapear, since the new Version is approved.

Is there an extension that does this, or can you point me to a place to get some ideas on how to implement this?

Thank

Johannes

I've done something similar using WorkflowPlugin. You just have to make sure that the workflow permissions are set the way you want it and use %WORKFLOWSTATE% to display the current state of the topic.
