Here's what to do. At the registration page for eComm America 2010, enter "JonArnold" after clicking "promotion code", and you should be all set. If this doesn't work, let me know.
Before moving on, a small point of clarification might be in order. I take it for granted you know what eComm is. Just to be sure, it's not ecommerce - this is not a conference about doing business online. eComm is short for Emerging Communications - it's just a lot easier to say that.
The long form may be a bit of a mouthful, but there's no better way to spend 3 days filling your head with ideas and inspiration that will/should change the way you look at the world of communications.
