How can I make f.error_messages work here, or should I use flashes?
If so, what should override in the sessions_controller?

<h2>Create an account</h2>    
<% form_for resource_name, resource, :url => registration_path(resource_name) do |f| %>
  <%= f.error_messages %>
  <p>
    <%= f.label :email %><br />
    <%= f.text_field :email, :class => :big %>
  </p>
  <p>
    <%= f.label :password %><br />
    <%= f.password_field :password, :class => :big %>
  </p>
  <p>
    <%= f.label :password_confirmation %><br />
    <%= f.password_field :password_confirmation, :class => :big %>
  </p>

  <p><%= f.submit "Create", :class => :submit %></p>
<% end %>

PS. f.error_messages for Creating an account works totally fine.
