continuum 1.1 and guest user

[deckrider+mvn]

I would like to just have 1-2 admins and everyone else can be guest
for continuum 1.1.

This seemed possible in continuum 1.0, but I must be missing some step
to know how to do it with continuum 1.1.  After I log in the first
time to set up admin, I'm still not understanding how to log in so as
to become guest (as well as how to give guest more privs).

Thanks!
