The 24h thing is not ideal for obvious reasons and that setting being enabled was not the plan. It is going to be turned off. Sorry for that surfacing.
The auto closing was only enabled for questions that had been resolved by the way.
Meanwhile though we’ve started deploying some other updates. You will notice that there have been some forum UI updates today. There is now a notification entry in the left nav too (links to forum notifications) and the top of the forum has an easier to understand navigation and bread crumbs.
Some of this is still currently being deployed so as of right now you will still notice some inconsistencies between sections of the site or some things not yet working all the way (notifications), so hold on a little bit but we hope this will create a clearer navigation.
If you notice any issues or such with this change, or functionality that you can no longer find please ping me and we will get it addressed.
Next up are suppose to be the post previews and likes that are shown in the picture earlier in this thread.
We are also looking at a small tweak in terms of how user names vs display names are shown on the forum as that is currently inconsistent and confusing.
