Hi,
I have a mambo site where I'd like to use smf only for managing users with special access levels.
I'd also like to install and use community builder to use for allowing guests to register with my site.
So basically I'd like to have smf only available to a few users, those who have special permissions, and I'd like regular registered users not to be able to see smf.
Is what i've described possible?

Yes, this is what I've done. But I want my admins to be able to login only once. I'm confused as to which login module I need to use (mambo, community builder, or mambo-smf bridge)?
