Not sure why they couldn’t have been ready when the product shipped? But they are there now.
Now I just need to persuade Adobe UK Licensing that my MVLP Studio 8, 24 month subscription sold to me when my DEVNET account expired does in-fact cover this upgrade to CS3 Web Standard. I’ve been playing email ping-pong with them over this for the past couple of weeks. Hopefully this will be resolved before my trial versions expire!
