Marketpress: where to find the registration for new clients?


I am testing out to checkout my products and I can't seemed to find the regsitration button. Where can I find it because there is only the login button. BTW, I am not log in as an admin when I check out.

Plus is it possible to add/store the name and email address of the customers who bought from "Checkout Directly"? Because in the other theme I bought, when you check out directly, the names and email address of your customer were stored in the wp database and then I can use it as a mailing list and so I can send them some newsletter via a newsletter plugin.

Please let me know how I can do it here since this is a much better ecommerce,.
