Awesome! Can I preview the Spanish? or have someone from my team provide it?
If I turn it down to 0 and 0, will it show on the topic that a user lands on? 
Small comment, but the word track : 
sounds a bit invasive, as opposed to remember or store. But perhaps that’s too subjective.
Does this show up on any page of the site or only on topics? I think it makes more sense for topics only, as might be out of context on category top level pages.
Still wondering if there’s a way to emulate a Sign Up link via some javascript function / anchor tag. I would like to include them in my welcome topics and perhaps some other places.
