+    # DEVELOPER's NOTE:
+    # Normally, to exclude a field from an Admin form, we could simply utilize
+    # Django's "exclude" feature.  However, it causes a "missing key" error if we
+    # go that route for this particular form.  The error gets thrown by our
+    # custom fieldset.html code and is due to the fact that "exclude" removes
+    # fields from base_fields but not fieldsets.  Rather than reworking our
+    # custom frontend, it seems more straightforward (and easier to read) to simply
+    # modify the fieldsets list so that it excludes any fields we want to remove
