 {% capture whats_the_point %}
 
 * Use forms with inputs to gather data from a user.
 * Send data to the server, declaratively or programmatically.
 * Get the response from the server with HttpRequest.
 * Handle communication asynchronously with Futures.
 * Use HttpServer to set up a server to listen on a port and host.
 * Use CORS headers to set access permissions for each request.
 * Use Polymer data binding to sync form data and Dart data.

 The request gives you an innocent stare and displays "No server"
 because you are not running the server on your machine.
 Let's fix that.
 
 ###Run the server
 
-Download or copy the source code for the basic server program
-from the github repository:
-<a href="https://github.com/dart-lang/dart-tutorials-samples/tree/master/web/forms/slambook/bin/slambookserver.dart"
-   target="_blank">slambookserver.dart</a>
+Get the source code for the basic server program,
+slambookserver.dart,
+from the
+<a href="https://github.com/dart-lang/dart-tutorials-samples/archive/master.zip">
+ tutorials samples
+</a>
+download.
 
 Run the server program from the command line:
 
 {% prettify %}
 % dart slambookserver.dart
 Listening for GET and POST on http://127.0.0.1:4040
 {% endprettify %}
 
 Now, you can try submitting data again with the slambook app above.
