I am using 4.8.0 and would like to have users retrieve password by giving their email ( as I understand by the method below)
_____
requiresUniqueEmail field in the web.config file to true ( requiresUniqueEmail="true" ). The web.config file is located in the root folder of your DNN installation.
To find out if your portal enables retrieve password using email address check the REquiresUniqueEmail option under User Accounts Settings.
My Question is As I did not have the setting <requiresUniqueEmail> set to true when the website went live and now have over 1,000 users. can I simply ensure no emails are duplicate in the database and then set the <requiresUniqueEmail> to true. or will I cause a problem or even crash my site??
any help appreciated.
Many thanks
