...erated page, added missing app/views/answers/edit.html.erb, added habta relationship to answer model, created migration for answers_users table, added current_user to list of users in the answers_controller create and update methods, added display of users in app/views/answers/show.html.erb, added before_filter to questions_controller so that you have to sign in before creating or editing questions. Access still needs to be blocked in the answers_controller as you can now access answers without signing in.
