I have a forum that is visible only for members of group A and moderators~.
People of this group are starting topics that are evaluated by our moderators.

We want to add information about if that topic is already evaluated or not – visible from topic list in this forum. What more we want every member of A to be able to set topic to ‘unevaluated’ – it’s possible to make another evaluation on demand (anyones from the group).

How can I achieve it?
