That's really cool.

For the connecttous.co link it would be nice if it was clear that it will actually send email to the addresses entered in the fields - it's not just a demo/toy. I may have inadvertently spammed someone when I was playing around with it.

Sorry, it actually works. The point of the demo is to show the Coils framework works end to end, and has full MailChimp/Mandrill email integration too

Wow. It's cool that it shows you which part was re-rendered. And it's great to see that my Elm prototype inspired someone.

Glad you like it! I think your Elm framework has inspired alot of people. Elm and LightTable (the Clojurescript development environment) are my two big sources of ideas right now! Thanks to you! :)
