title: Admob ad unit id big confusion
body: <p>I have a unity3d plugin for integrating admob ads. Its asking for ad unit id in this format "ca-app-pub-XXXXXXXXXXXXXXXX/NNNNNNNNNN" but the publisher id of any given app in my admob account is in this format "a15854eg4d5rh64". What is my ad unit id? I'm totally confused and search all over the search engines without any answers. I'm literally smashing my head and search for a working solution since 6 hours straight. </p>
  
  <p>Any help?</p>
