It seems to me potentially confusing that the Worldspot splash page has 2 logins and an option to "register" with Worldspot.
I've always thought that a welcome/splash/landing page should be as simple as possible, only containing information that is needed to connect to the Internet.
I think that access to Hotspot administration should be removed from the landing page, administrators and enquirers could easliy register on the Worldspot website, and the link to the site doesn't confuse Hotspot users.
