By default, customers have to log in on a separate page, not on the main splash page. This is better because when the customers see "Click here to log in", then the link goes to a page where the login box is displayed only so it's very straight-forward.
It is now possible to combine (merge) the login box with the main splash page, so the login box will be displayed above the package selection or voucher activation box. Login links will lead the customers back to this page.

On the screenshot above, you can get the idea. This is a combined splash/login page with the Ocean Blue Skin.
