title: How I can know the limit for groups read?
body: <p>I'm working into the migration of a large list to Google Groups from Google Apps Script.</p>
  <p>After some creation of members, i'm having this Exception:</p>
  <blockquote>
  <p>Exception: Service invoked too many times for one day: premium groups
  read.</p>
  </blockquote>
  <p>There is one way to know the available quote of reads for integrate this verification into my code.</p>
  <p>This is my function:</p>
  <pre><code>function readSheet(){
      var sheetId='MY-ID';
      var sheet = SpreadsheetApp.openById(sheetId);
      var toIgnore = 1;
      var mData = sheet.getDataRange().offset(toIgnore, 0, sheet.getLastRow() - toIgnore).getValues();
  
      for (var i = 0; i &lt; mData.length; i++) {
          /*Here verify quota*/
          addUsertoGroup(mData[i][0]);
      }
  }
  </code></pre>
  <p>How I can achieve this?</p>
