I have now entered all those with email addresses into the website. I have allocated usernames made up of the initials of your full names followed by in most cases the figure 1. In half a dozen cases where people share initials, it will be a 2 or 3. If you can’t find out by trial and error, or if your email address is wrong, email me at email@example.com and I will sort it out. As an example of a username, James William Atkinson-Smith will be JWAS1.
In order to determine and perhaps to change your password you will need to enter your email address and your username. You will then receive an email with a new password which you may change to something that you can remember (but not too easy). Note that usernames are not case sensitive but passwords are!
