+<h2><a name="backporting">I'm using an ancient version from the dawn of time and something's broken.  Can you backport fixes for free?</h2>
+
+<p>Variants of this one get asked a lot.</p>
+
+<p>The purpose of the BusyBox mailing list is to develop and improve BusyBox,
+and we're happy to respond to our users' needs.  But if you're coming to the
+list for free tech support we're going to ask you to upgrade to a current
+version before we try to diagnose your problem.</p>
+
+<p>If you're building BusyBox 0.50 with uClibc 0.9.19 and gcc 0.9.26 there's a
+fairly large chance that whatever problem you're seeing has already been fixed.
+To get that fix, all you have to do is upgrade to a newer version.  If you
+don't at least _try_ that, you're wasting our time.</p>
+
+<p>The volunteers are happy to fix any bugs you point out in the current
+versions because doing so helps everybody and makes the project better.  We
+want to make the current version work for you.  But diagnosing, debugging, and
+backporting fixes to old versions isn't something we do for free, because it
+doesn't help anybody but you.  The cost of volunteer tech support is using a
+reasonably current version of the project.</p>
+
+<p>If you don't want to upgrade, you have the complete source code and thus
+the ability to fix it yourself, or hire a consultant to do it for you.  If you
+got your version from a vendor who still supports the older version, they can
+help you.  But there are limits as to what the volunteers will feel obliged to
+do for you.</p>
+
+<p>As a rule of thumb, volunteers will generally answer polite questions about
+a given version for about three years after its release before it's so old
+we don't remember the answer off the top of our head.  And if you want us to
+put any _effort_ into tracking it down, we want you to put in a little effort
+of your own by confirming it's still a problem with the current version.  It's
+also hard for us to fix a problem of yours if we can't reproduce it because
+we don't have any systems running an environment that old.</p>
+
+<p>A consultant will happily set up a special environment just to reproduce
+your problem, and you can always ask on the list if any of the developers
+have consulting rates.</p>
