I am designing a simple web application. The only main function is displayed in homepage, together with other product feature promotion. On the top of the page, there are two buttons, for sign up and login respectively.
Our marketing goal is to encourage users to register/sign up. Now when users click on login, the page will have a popup window for users to input email and password. But for sign up button, I am not sure which method is more encouraging and convenient, popup window or new page?
