Or the threads can be as they are and any council member wishing for feedback can make a thread in GD and link it to their Council thread, with a ‘I would appreciate any thoughts and feedback on this’, which then makes a link right on the council thread main post linking to the GD discussion for it that can be followed for any feedback.
And any non-council person that wishes to discuss a council thread can also link the thread in the post, which not only notifies the thread creator as mentioned, but also as noted above adds a link section under the main post of the council thread, so any post discussing it is viewable and followable from it.
And as such council threads aren’t turned into a mess, a whole another area to have to moderate isn’t made, and the council thread has links to any related discussion posts right on it to follow for discussing it.
For example (and my apologies for the ping to the council member I’m linking for the example), if a council member (or any GD person) wanted to get feedback on say being unable to cage new pets, a council thread
Simply linking that thread now has pinged that thread creator, and this thread now shows as a link on that council thread as having talked about it, so if this was a dedicated thread to talk about that topic, a link to the discussion post for it would be right there.
