  '<p style="margin-bottom: 12px;"><strong>Dear SBIer,</strong></p>' +
  '<p>You are receiving this (weekly) reminder because you are using an outdated browser<strong>*</strong>.  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 6 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 Site Build It!, 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."  Our recommendation?  Upgrade to the latest version of one of the following browsers (the minimum requirement for each browser is in brackets - the latest update is more advanced than that)...</p>' +
  '<ul><li>Firefox (versions 2 and up)</li><li>Internet Explorer (versions 7 and up)</li><li>Safari (versions 3 and up)</li><li>Google Chrome (versions 1 and up)</li><li>Opera (versions 9.5 and up)</li></ul>' +
  '<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>' +
