+    <h3>What if I need more nodes than are free?</h3>
+    <p>
+    For example, say you need 50 nodes but there are only 40 free. In
+    general, getting this many nodes is going to require intervention
+    from Testbed Operations, if only so we can ask other experimentors
+    to free up nodes, if possible. Please send us email if you are not
+    able to able to get the number of nodes you need for your experiment.
+    </p>
+
+    <p>
+    Another alternative is to use the
+    <a href="tutorial/tutorial.php3#BatchMode">Batch System.</a> 
+    If your experiment is amenable to being batched (does not require
+    human intervention to start and stop), then you can submit a batch
+    request, which will be serviced when enough nodes become
+    available.  Typically, you would start out with a few nodes,
+    getting used to the batch system and creating whatever scripts are
+    needed to make the experiment batchable. Then scale up to larger
+    numbers of nodes. Thats the easiest way of getting a lot of nodes!
