The ability to move forum topics and leave a "shadow copy" is great. However, I've noticed that after a while, shadow copies can kind of clog up a forum.
What I'd like to do is delete some shadow copies that have been around for a long time (people know by now where the post is), but without deleting the original post (that has been moved).
Even better, I'd like to set something up in a custom module to automatically delete shadow copies after a certain period of time.
Can anyone point me in the right direction?
