Re: Double passwords
I’ve noticed probably the same problem.
Buddypress has no welcome email by default. You can remove the Buddypress function that kills the welcome email, but then the password in the email is wrong.
I don’t believe this is a WPMU issue. It must have something to do with Buddypress’ changes to the registration process. And I’m also pretty sure that themes have nothing to do with how a password is grabbed from the database and put into an email.
