 >> Figured it out.  Can you comment on the code below?  Thanks. -- [[MarceloMagallon]]
 
+So, I have some code, included below.  For some reason that I don't quite get it's not updating the wiki page after a submit.  Maybe it's something silly on my side...
+
+What I ended up doing is write something like this to the page:
+
+    [[!blogcomment from="""Username""" timestamp="""12345""" subject="""Some text""" text="""the text of the comment"""]]
+
+Each comment is processed to something like this:
+
+    <div>
+        <dl>
+            <dt>From</dt><dd>Username</dd>
+            <dt>Date</dt><dd>Date (needs fixing)</dd>
+            <dt>Subject</dt><dd>Subject text</dd>
+        </dl>
+
+        <p>Text of the comment...</p>
+    </div>
+
+.  In this way the comments can be styled using CSS.
