Web design ecommerce question. How do I set up individual accounts for each customer?

[Wallter]

I am a web design student and I have to set up an ecommerce site. I have the shopping cart thing down, but I would like to set it up so each person can create there own login/account. I really have no idea how to do this. Can someone help me out please?

I think it is an inbuilt option in most of the shopping cart CMS you would use for its development. They have inbuilt facility for making group of different people and specifying restriction on it. So prefer to use popular ecommerce CMS like Magento and OsCommerce to develop shopping cart which would require less coding.
