I just noticed some new posts at the bottom of a VERY OLD thread (TER White Lists ... started 7 years ago).  
.
Hazel, Nadia and any other newbise: Click the "+ New Thread" button to start a new thread ("topic") to introduce yourselves and ask your Qs.  
.
And read "TER's Instruction Manual." First, click the "Go back to forum" button (below).  Then, on the top right, choose "Tree" mode if it isn't already selected. "TER's Instruction Manual" will be the top post (locked to the top) in tree mode.  
.
GOOD LUCK!

...on "Some Info For Providers" which is that seven year-old thread you mentioned.  They posted to that thread instead of this forum.
