noutram1000 - I was knee deep into reseaching rare earths and their uses and applications and also the complexities involved in their separation and extraction.  In fact my researching started 2 years prior to 2001 in 1999.  Knew very little about them, however in 2013 it is a very different situation.  My knowledge about rare earths is about as good as it gets for an average Joe or for that matter a Mary.
