Aggregator could automatically expose its aggregates as prefixed attributes:

<%= form_for @profile do |f| %>
  <%= f.text_field :user_name %>
  <%= f.email_field :email_address %>
  <%= f.password_field :user_password %>
  <%= f.password_field :user_password_confimation %>
<% end%>

why have a separate api for combine, rather than just Profile having save? it is because you don't want to override a save method it would have inherited?
