Thanks for your plugin.
Could you please advice how I can set the minimum number of characters for the user profile fields like name, surname and password.
I would also like to know if it is possible to display a message when user try to register with e-mail which is already there?
Thanks in advance.
Unfortunately there is no option to set the min or max number of characters in user fields for registration. Also, there is no option to change default message about already existent email address.
IF you want, we can discuss an ability to add this option to our plugin via internal support.
