# Mongoid::Document model for dc_user documents.

# dc_users collection holds data about regitered users. Passwords are encrypted

# This model defines basic fields required for evidence of
# registerred users. Since it is implemented as ActiveSupport::Concern you are
# encouraged to further expand model with your own data structures.
