# Basically membership is a layer between the signup/login form, and
# the authentication layer, it uses the prop source of the users to
# store additional information about a user i.e. doesn't impact on the
# authentication source.
#
# Some membership features imply some extra properties for the user will
# be available; specifically at this time an email property.
#
# You also need a MailHost setup and ready to go for emailing stuff to users
