What do you see if you iterate over the members of the array, like this (in a
view, just for debugging purposes)?

	<%- @member_list.each do |member| %>
	<%= member.inspect %>
	<%- end %>

I am guessing that each member will carry its own hash of errors, and you should
see them when you do this. Then it''s just a matter of iterating them in
your view to build the error list per member.
