(1) only enables the starting url which is always done. Useless filter.
(2) The sub pages are: TP Worksheet: Up in Arms? -
<http://edition.tefl.net/talking-point/arms/> 
No /category/ so the filter does nothing. No sub-pages, no pdfs.
(3) The uploads are like: Talking Point: Up in Arms? -
<http://edition.tefl.net/wp-content/uploads/2010/10/TP_Up-in-Arms.pdf>
+uploads/*/*/* allows anything 3 (or more) levels down from uploads. Would
work except for (2)
(4) allows just pdfs from anywhere. Would work except for (2)
