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.
There will be a delay before you receive your activation link email.
You must use the activation link in that email
before you can use the account.
If you didn't receive your activation link, and it's been a while,
please sign up again and we will send you a new one (once the
activation delay expires).
If you've already created an account here via GitHub, please log in
using GitHub instead.
