Threads Auto-delete
 

The idea is allowing the moderators to schedule when the thread will be deleted it.

This is helpful for big forums, as I usually close threads and leave the reason in the last reply and delete later (so my users can learn & follow the rules), but the problem is that I forget to delete these threads or it becomes hard to find them in big busy forums. That's why it will be very helpful to allow us to schedule the deletion of the thread after x days/hours etc.
