π€This extension might be a great starting point for an expired posts extension. All one would need to change is at the set number of days either lock or soft delete the post. Lock would be fine. If only there was more time in my life. π€
Edit: I found a tiny bit of spare time and made some progress. I simply removed the checkbox. So once the number of days hits there's no way to reply. Next, I will try to figure out how to set the post to locked automatically. π Then, we have somewhat of an expired posts extension.
