It's been going for a few weeks now. I kept an eye on it for a while and was surprised/disappointed to see how little use was made of it; a few hundred matched at around 100% book was the norm. BF could do more to publicise it though - but they do put up the games affected at the top of the footie forum.
Edit: just checked and I can now see no mention of it. No wonder no-ones's using it!
