The vast majority of the time, this is because you’ve slightly mistyped or didn’t quite remember exactly how you signed in previously.
Remember that both the username AND the password are case sensitive. If you signed up as “JohnSmith”, then “johnsmith” will not work. Likewise with the password.
If you suspect that you have forgotten your exact password, please try using the Forgot Your Password? link to get a reset email sent to you.
If you’re are certain that you have the username and password correct, email us at firstname.lastname@example.org and we’ll look into it for you.
