I've been searching for a really long time and can't quite seem to find the right hack/plugin to solve my issues. I've constructed my wordpress theme as an open registration site, and members have the ability to change their email. Users do not have the ability to change it to an email that is always registered.
If a user changes their email after registration, there is no verification sent it just updates as long as the email is not already registered. What can I do so that after a user successfully registers and say 5 months later decide to change their email, they can't change it to some random email, or accidentally put it in wrong.
Emailing users will be a main form of communication. Thanks to anyone who can help.
