Looking for a component or theme that breaks discussions into phases like ideas, voting, building - for projects, applications, etc

I think you could do this with category permissions — have a category (or a subcategory) for each phase, with permissions like:

  • Idea Gathering: anyone can post and reply
  • Discussion: only moderators can post anyone can reply
  • Voting: only moderators can post, and the post contains a poll. No replies.
  • Building: posting limited by group to team members

And maybe you could use the kanban theme component in category mode with this — I haven’t tried anything like that, though.
