Filtering recent posts by language or area

I want to use a URL like this -

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?action=recenttopics;display=20

to see the most recent 20 topics, but I want to eliminate the ones in non-english languages (sorry, just can't understand them)

I tried adding some filters like "language=English" and a bunch of different trial and error combinations, but no dice.

Any idea how to do this? I tried...

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?action=recenttopics;display=20;**catselect=software** - no dice, still returns everything

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?action=recenttopics;display=20;**board=hardware** - nope. everything.

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?action=recenttopics;display=20;**language=English** - everything still.

I too would love if anyone has an answer to this. I use news gator at work in my outlook to keep up with th forums, I had to write a bunch of rules for outlook to disregard unwanted ones. Is there a more specific RSS feed ?
