I've been poking with the PM system a bit... and first of all, I must say I like the threaded PM system a lot. The reasons should be obvious, so yeah, I won't go into that.
But what bugs me is that weird things seem to happen when PMs are deleted. I can't access the whole thread, and I get this.
Both sides can't access the thread regardless of who's deleting it. And that's a prob, because one side might still need the info in the PMs. So yeah, is there a way to make it so that when someone delete a PM, the whole thing is still available to the other side?
