Woo Hoo! (I know, two Woo Hoo's in a row isn't showing much originality...) Feature Pack 1 (BETA) for Microsoft Commerce Server 2002 was released as a PUBLIC BETA today. You can get the code by walking over to http://www.betaplace.com and logging in as csfp1beta. You will need a passport account to do this.
Go eat some of our dogfood, and give me feedback! I'd love to pass it back on to the product teams.
