There are many times when a fossil-based project has need for an associated 'forum' Forth] being one example :) ).  Integrating external forum software with fossil is difficult; in addition, the knowledgebase provided by the discussions is then external to the repo.

I would like to have some manner of 'forum' capability inside fossil.  It need not be very complex, but having the ability to have groups of discussions, and show the contents grouped by discussion threads would be extremely useful to me.

I'm willing to work on adding such a feature if nobody else has; but I'm not sure what the proper underpinnings should be (and how to make sure the forum information gets properly cloned etc).
