It takes time for mods to see and sort a new story. In this case I think they'll realize it's just a signup page, remove the "Show HN" from the title, and bump it to near the bottom of the page.
It's better to give new stories some time near the top, otherwise legitimately interesting stories will fall through the cracks.
