Would Google Group tags be something you'd be interested in seeing used here? See https://support.google.com/groups/answer/2645570?hl=en. Enabling tags would allow all forum members to be able to label posts with tags in order to find related posts more easily.
If so, what kind of tags would you like to see? Some ideas would be to mark threads as "Resolved" or tag by popular subjects, such as "3D Tiles".
Or is all of this just too much overhead? We'd like to hear your feedback.
