Thank you for sharing. It's always helpful to see what people respond to in these types of tests. It appears as though the word "contribute" is at the core of your lift. It's a much more meaningful term than the vague "sign in" -- and it gives visitors a lot more information on which to base their decision to click (or not). The CTA copy also does a nice job of supporting your headline. Your statistical confidence is a little low, however. At those levels, you're taking a leap of faith. Good directional data, sure, but I've seen plenty of tests go from 84% "chance to beat original" to flat in a few days.
