Now that we can build and evaluate datasets it might be nice to let people discuss them. The simplest way to do this at first might be to just have a single discussion thread per dataset, which people can access from the overview, view, and evaluation tabs.
As a more advanced feature we could have separate sub-threads for each class, and for the evaluation screen and then combine all of these threads together on the main dataset page.

We have 2 options for implementing this - one is to write it ourselves, and the other is to use an existing discussion as a service system which we can include on the page. We should look at the same tools that MB was looking at for on-site discussion.
