Kanban for Code Interactive, email follow-up needed.

I've been rereading The Lean Startup and I've come across the kanban method that's suggested. I should really start using it for working on Code Interactive. I'll set it up on github

I have also realized I've made the same assumption in regards to lazy registration as is shown in the example of Grockit. I was thinking earlier how I'm missing out on collecting emails because of all the users that don't login, but I've removed the login to favor getting people to try courses, over collecting users. However, it's probably worth testing if the requirement for users to login would affect conversion rates (i'm counting the chapter 1 finished funnel, which is at miserable 2% now). I should probably look into that, but doesn't seem like a priority. A bigger concern is the lack of users who actually use the product.

I should send the email to people who subscribed to calculator and todo.

Took a look at the subscriptions for these two. Only one, for todo, with an empty email. A sad way to end the short, unproductive session.
