[ic] Email and Unique Account settings

[EEUL Support]

I have gone though several dozen old messages using the search feature 
and I am still at a loss figuring out how the eliminate people creating 
duplicate accounts via checking for a unique email address.

Can someone give me a simple set of instructions for modifying 
new_account.html or another area of IC to check the email address 
against  UserDB.

I am running IC 5.4.2 and have tried the email=unique in several variations.


Any Ideas?
