  '<p>You are receiving this (weekly) reminder because you are using an outdated browser. (See the NOTE at the end of this e-mail for details.)</p>' +
  '<p>We all get attached to our browsers and tend to delay upgrading until "later."  But here\'s why this message is important...</p>' +
  '<p>Site Build It! software advances constantly.  To give you <em>fast,</em> cutting edge functionality with the click of a button, and the best user experience possible, our tech team uses advanced JavaScript and Ajax.</p>' +
  '<p>Internet Explorer 7 and other older browsers do not interpret advanced programming well.  Their performance is slow and unstable.  Upgrading will result in fast and stable behavior, not only in SBI!, but in many other advanced programming environments, such as Google AdSense.</p>' +
  '<p>In short, you need what is called a "modern browser" to handle "modern Web software."</p>' +
  '<p>Please upgrade to the latest version of one of the following browsers...</p>' +
  '<ul>'+
    '<li>Firefox</li>' +
    '<li>Google Chrome</li>' +

That means that we will  support the current and previous major releases of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we\'ll begin supporting that version and stop supporting the third-oldest version.</li>' +
          '<li>We recommend that you do NOT use Internet Explorer due its weaker performance, but if you prefer to continue using it, please upgrade to the newest version.</li>' +
      '</ol>' +
  '</div>' +
  '<p>You will rejoice at the difference, not just at SBI!, but at every other site that uses advanced Web programming.  More and more major sites are using this type of programming.  So take advantage of it and upgrade now.</p>' +
  '<p>It\'s easy and simple to do.  You automatically keep all your favorites, for example.  It\'s also easy to switch to a different browser since they all offer the ability to import each other\'s bookmarks/favorites.</p>' +
