It may be possible to rename the second (newer) "resource graveyard" forum, giving it another name so as to reduce confusion. That aside, the underlying principle should remain intact: rejected tutorials must remain separate from other rejected submissions.
There's also another "Graveyard" (of sorts) in which other unacceptable content is buried: the Recycle Bin.
That separate forum contains threads and / or posts deemed to be inappropriate (WoW model requests, map de-protection discussions, etc).
