title: Elmah error logging, can I just log a message?
body: <p>I just installed Elmah (<a href="https://code.google.com/p/elmah/" rel="noreferrer">https://code.google.com/p/elmah/</a>) for my ASP.NET application.
  Is it possible to log a message without creating an Exception first?</p>
  
  <pre><code>catch(Exception e)
  {
      Exception ex = new Exception("ID = 1", e);
      ErrorSignal.FromCurrentContext().Raise(ex);
  }
  </code></pre>
  
  <p>So is it possible to do:</p>
  
  <pre><code>ErrorSignal.FromCurrentContext().log("Hello I am testing Elmah");
  </code></pre>
