This is also a group on Facebook, which I just joined. I have listened to the first one, and I have all of them on my iPod. If you're learning to speak Dutch, this is the way to go. My own learning is more passive, reading and listening. If I have occasion to go to a Dutch speaking place, I'll listen to the rest of these first and practice that way. Again, I'm in a region where there are very few Dutch speakers. On the Facebook group site, there are lots of tips and recommendations, which you can use or not according to your learning style.
