title: how client/server communication works with meteor/nodejs
body: <p>I'm learning about Meteor. Right now I'm trying to figure out how the client/server communication works, I have a file under [root]/server with all the information to connect to DB (user, password, host, port) also I have the following line of code to test this "communication"</p>
  
  <pre><code> var getUsers = function(name) {
             return "Hi. I'm " + name;
        };
  </code></pre>
  
  <p>and in my root folder I have:</p>
  
  <pre><code>console.log(getUsers("Juan!"));
  </code></pre>
  
  <p>however I'm getting "Uncaught ReferenceError: getUsers is not defined " error. so the question is, What I'm doing wrong????????</p>
  
  <p>thanks in advance for any help or hint</p>
