@julian Just happened to me when I first registered, I logged out and back in and I was able to edit.

I felt like heroku was a bit of a pain in the ass to develop on (that's just me).

If you were just looking to mess about for a little while then you can google for a one month free coupon on digitalocean (no purchase necessary)

If you're sticking with heroku, have a look at our wiki for an installation guide:)

https://koding.com is a free development VM (Only running when logged in) I did manage to get a NodeBB instance running just by running the commands in GitHub.
