Looks like the conversation doesn't work, it returns the following when trying to post a message:
Invalid Block Object.
There doesn't seem to be any add-ons to do it, any ideas how I can do this?
From what it looks like, there will soon be improvements made to the Conversations feature so that a forum will be possible.
Not good news, I need to quote for a project with no idea how I'm going to do the forum now.
Happy to contribute in any way I can :)
