In reading the feedback from publishers on the forums and in our support queues, the number one product request was the ability to use referrals in formats other than the current buttons. In particular, publishers asked us for the ability to refer via text links. So I'm pleased to announce that we now offer text links as a format option for AdWords, AdSense and Firefox referrals. You'll notice the new text link formats show up for US English; we'll be adding other languages shortly.
Please keep the suggestions coming.
