I don't think that has been updated in a LONG time now. It seems the person has lost interest, or just doesn't have the time to do it anymore. I can't say as I blame him, frankly, as it was a huge undertaking. It had to be really dragging his free time.
Of course, if he could offload that stuff to the wiki, anyone could update it. Not all of it, mind you - there are some things there that shouldn't be published, for reasons I can't discuss here. But all of the 'public' stuff could be done...Mike
