A few users have not been assigned the minimum role of "Authenticated user" due to misconfiguration. So I cant include them in newsletter.

The new users are being assined the role correctly but there are a dozen users who were not assigned the role of "authenticated user" due to bad config of Adv. Users module settings

Now i have no option of how to give them the role of "authenticated user"

One option that i see is deleting and creating the username again . But how do i know their passwords?

i dont want to reset their password.
