Preventing Password from Being E-Mailed


I've noticed that, even when we allow users to select their password at signup (using your plugin), the password is e-mailed to the user. Yes, it's the right password (the one they selected at signup). However, in the past we recall that in this case that password was not e-mailed. Instead, the message said something like, "Password: The one you selected at signup." Of course, we prefer this approach for security.

How can we make it this way with the current version of the plugin?
