Weekend Learning: Useful R12.2 Documents

There are SO many things in note 1585889.1 on MOS "Useful 12.2 Documents For Customers And ATG Support Engineers" that I can't even begin to explain it.  I'm making this a favorite in MOS so I can keep tabs on this to stay on top of changes coming down the road with the various versions of R12.2 as I know that we will be upgrading someday even though we JUST got done with an upgrade.  I would rather have things in the back of my mind for when we start planning, and keep this around for handy quick reference later.
