New subforum: Tarpit

Hi all,

I added a new subforum to the admin forum called “Tarpit”. The thing is that phpBB does not allow for deleting posts recoverably, so if a moderator feels a post should maybe deleted but the violation is not 100% clear - a borderline case, so to say - it should be moved to the tarpit instead of being deleted. That way, moderators can review and discuss the post.
Posts in the tarpit are automatically deleted after 30 days if not moved back to another forum.
