"Where can I find these emails? Would be nice to have in case someone questions the validity of the test."

Back in June when Delta Gate Agents were creating issues over the tests, several people posted their EHAS emails re the IDNow test being totally valid on various Facebook groups in Cut and Paste or PDF formats. The funny parts were the stories people posted along with them - like showing the Gate Agent their EHAS email copy, and the Gate Agent asking if they could make a copy of it, etc.
