+      <para>
+       <literal>w</literal> is used whenever you perform a "safe" operation
+       (<function>MongoCollection::insert</function>, 
+       <function>MongoCollection::update</function>, 
+       <function>MongoCollection::remove</function>, 
+       <function>MongoCollection::save</function>, and
+       <function>MongoCollection::ensureIndex</function> all support safe 
+       options).  With the default value (1), a safe operation will return once
+       the database server has the operation.  If the server goes down before 
+       the operation has been replicated to a slave, it is possible to lose the
+       operation forever.  Thus, you can specify <literal>w</literal> to be 
+       higher than one and guarantee that at least one slave has the operation
+       before it is considered successful.
+      </para>
+      <para>
+       For example, if <literal>w</literal> is 2, the main server and one slave
+       must have a record of the operation or the driver will throw a 
+       <classname>MongoCursorException</classname>.  It is tempting to set
+       <literal>w</literal> to the total number of slaves + master, but then if 
+       one slave is down the op will fail and an exception will be thrown, so 
+       usually <literal>w=2</literal> is safest (master+1 slave).
