Hello all,
I have a question. I guess this worked pre 2.6; I don't remember the
last time I used it, but it was a while ago, and now it's failing.
Anyone mind looking at it and telling me what's going wrong? Also, is
there a quick way to match on a certain site? like links from google.com
and only output those?
