+<p>The number entered here determines how many &quot;upload boxes&quot; are 
+    shown when the student submits a peice of work. The number can be zero, 
+    that is no attachments are allowed. If attachments are expected, the number
+    is set to 1, 2, up to 5. Normally the number will be 0 or 1, but in some 
+    assignments the students may be asked to submit more than one attachment.</p>
+
+<p>If the number is set to 3, say, and the student only attaches two files to 
+    their submission, the two files are attached and there is <b>no</b> warning 
+    message. Thus, when submitting work (in a single operation) students can 
+    attach an arbitary number of files to their submissions, up to the maximum 
+    number given by this option.</p>
+
+<p>Note this option does <b>not</b> set the maximum number of attachments a student 
+    can add to their submission. It just determines  how many &quot;upload 
+    boxes&quot; are shown. The student is free to add more attachments to their
+    submission by editing that submission. This would be unusual.</p>
+
+<p>The default value for this option is zero, that is no attachments are 
+    required.</p>

+
+<p>This link re-calculates the &quot;Grading grades&quot; of all the student 
+    assessments which have a corresponding teacher assessment. Normally it is
+    <b>not</b> necessary to action this re-calculation. Student assessments
+    are automatically graded after the teacher has assessed the relavant piece
+    of work from the student.</p>
+
+<p>If, however, the Grading grades are felt to be too high or too low the 
+    teacher may wish to change the &quot;Comparison of Assessments&quot; option 
+    (by Updating the Exercise). The default value of this option is 
+    &quot;Fair&quot;. If the grading grades are too high then setting the 
+    option to either &quot;Strict&quot; or &quot;Very Strict&quot; will reduce
+    the grades. Or alternatively if the grades are too low, setting the option 
+    to &quot; Lax&quot; or &quot;Very Lax&quot; will increase the grades.</p>
+
+<p>If a change to the Grading grades is required the steps are:
+    <ol>
+    <li>Update the Workshop with the new value of the Comparison of Assessments
+    option;</li>
+    <li>Go to to the Workshop's Administration page and click on the 
+    &quot;Re-grade Student Assessments&quot; link.</li>
+    </ol>
+    The new grades will be displayed. These process can be safely repeated.</p>
