Sign up

If you have a GitHub account, you can just use it to log in instead (a first-time GitHub login will automatically sign you up).

If you don't want to log in with a GitHub account, you can sign up here instead (this creates a custom account using your email address). If you sign up, your name will be shown publicly, and you can change your name at any time. Your email address will be kept private and only used for badging-related interactions; we will not provide it to third parties unless it is legally required.

If you didn't receive your activation link, please sign up again and we will send you a new one. If you've already created an account here via GitHub, please log in using GitHub instead.
