How can I add a Sign_up box exactly like the Log in box on the right?
Default template already added a register link on the top right of your page. And there is no way to add a sign up box on your front page. Registration process only works in its register page (yoursite.com/index/3)
How can I move the header box to the left? How can I make it transparent? How can I change the top picture (the books with the green background)?
