I need to write the hooks that will override the address forms for the shopping cart check out screens. Their needs to be an option to save the address at check out if it is new and also select past used addresses from a drop down. I have the forms setup and the database connections made, so the only major thing to do is the hooks. There has been some talk about normalizing the addresses so the name is stored in a different table. I think that would be a good idea, but it would take a little bit more work.
