I have installed the Marketpress eCommerce on my website here:

Every thing else is working fine. I am able to fine the
Store page:
Shopping cart page:

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 :
I want to show Create Store function to my registered user in there profile page here:

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.
