title: SignalR(Hub) can send a message except signal maker?
body: <p>I'm studying SingalR(<a href="https://github.com/SignalR/SignalR" rel="nofollow noreferrer">https://github.com/SignalR/SignalR</a>).</p>
  
  <p>I'm really want to send a message to all connection <strong>except the person who makes a event.</strong></p>
  
  <p>For example,</p>
  
  <p>In Chatting application, there is three client(A,B,C).</p>
  
  <p>Client A type a message, "Hello" and clikc submit.</p>
  
  <p>Clients.addMessage(data); send "Hello" to All Cleint(include cleint A)</p>
  
  <p>I want to send "Hello" only Client B and C.</p>
  
  <p>How can I achieve it?</p>
  
  <pre><code>// I think this can get all Clients, right?
  var clients = Hub.GetClients&lt;Chat&gt;();
  </code></pre>
