Hot to setup a store for multipress like http://etsy.com/

I have installed the Marketpress eCommerce on my website here: http://dtflea.com/

Every thing else is working fine. I am able to fine the
Store page: http://dtflea.com/store/products/
Shopping cart page: http://dtflea.com/store/shopping-cart

But I dont know how do I set up it as right now it's not showing it in navigation and any where.

I want to make my store like : http://www.etsy.com/
I want to show Create Store function to my registered user in there profile page here: http://dtflea.com/phillip/

When a user will be login he will be able to see Create Store or Manage Store option in the profile which is right now not working. I read out all the doc and instruction and not found anything helpful for this.

Let me know how do I figure out this.

Thanks,
