Gillianren is right at this thread being two years old. However, the poster everyone is responding to HypothesisTesting, who has very recently bumped* this thread, with a slightly relevant post. Therefore the current 'discussion' (as far as you can call it one) is not necromancy, but it's a new discussion in an earlier started thread.

* Where I hang out posting a new post in a very old thread is called bumping. Bumping it back to the first page of a forum, or something. I don't really know where the term came from.
