Well the updates to the E-Commerce module is coming along great. A few days ago we had the product module working, and after a little bit of bug fixing for PHP5, I managed to get it all running, and I was able to create products.
This morning I spent a little time and got the checkoutapi working (well sort of) and now you can get all the way though to the review page without an error. There needs to be some work on the tax module, and then we should be able to create transactions.
There is a lot of things that need to be worked on.
To all those people who have helped out so far. Thanks very much but there is still plenty of work to do.
