If you've forgotten your password, you can reset it by following these steps:
- Go to the login screen.
- Click the 'Forgotten your password? Reset it via email' link under the 'Password' box.
- In the dialog that appears, enter the email address that you normally use to log in. This will send an email to that address.
- Check your inbox for the new password request email, and click the link it contains. (If you don't initially see it, you might just want to check your junk folder, in case it's been put in there.)
- On the page that loads, enter your email address again and enter a new password, followed by confirming that password.
- Click Update, and then login using your newly reset password.
