Michael,

The RememberProfileLayer sets up some users, and references are assigned
in the RememberTestBase class (in tests/base.py). If your test class
inherits from RememberTestBase, you can access them like:
self.portal_member
self.blank_member
self.admin_member

It's probably easiest to have your test class inherit from that one, set
your layer to your custom layer, and then add your tests there.

You may want to also take a look at some of the other tests to see how
the members are being used. I believe that most tests make use of the
self.portal_member, whose user id is: "portal_member".
