I'm writing a custom signup script for users to register with on my MU-setup.
One problem I'm having is that
wpmu_signup_user() sends the password activation email but it doesn't return the user ID which I need for the rest of the script. - It's my understanding that this doesn't create the user account, just an entry in the "signup" table.
The other way I've tried is using
wp_create_user() which returns the user ID I need (as it creates the user properly) but no email for the user.
