If you want to change your password, do the following:
1. If you aren't already, log in by clicking on the + in the top right hand corner of your website
and login using the login form provided.
2. Click on your name at the top and a dropdown menu will appear. Click on "My account".
3. You'll be presented with a popup modal with your account details shown. Click on the little edit icon (pencil) next to your password (starred out for security reasons).
4. You will be presented with 3 text inputs. In these you must enter your current password (to ensure it is you doing this) and your new password twice (to ensure you typed it correctly). Click on "Change Password" to commit your changes, or Cancel if you choose to not change the password.
Once this is done, you can close the modal window as your changes are already committed.
