We had an issue this morning with our outbound mail server. It is now back online. If you signed up for an account or requested a password reset email between then and now you probably didn't get the email. To recover your account:
If you needed your password reset you can follow the password reset flow on the log in modal as normal.
If you signed up for a new account and never received your account confirmation email, you can confirm and set your password by following the password reset flow on the log in modal as well. Click the "Log In" link at the top of the page, then click the "Forgot Your Password?" link under the form fields, enter the email address you created the account with, hit submit and then click through the link in the email sent to your inbox.
Apologies for any inconvenience,
