Sorry. I didn't mean to confuse anyone.
I mean the user log in. Where the user (visitor) will log in (or click to register) when they want to view their personal page.
Most visitors to my site are coming to go to their personal page and start shopping their favorite stores. I want them to look around the home page for a little before going to their page, especially to see the new stores list. So by putting the log in next to the new stores list, I can get them to take a look at it. That's the theory anyway.
