When it asks about a domain, I have always said “I need one”
Choose a domain e.g. myschoolapps.co.uk and press next. This will be roughly £10 a year.
You then need to enter a username and password for the (super) admin account.
Feel free to use your name, you can add other super admins later.
You will then have a license agreement to read through. Agree and continue.
You start on a 14-day trial. When you sign in, you are given the option to purchase your domain (£10 a year) and this will change it from a trial to a proper account. It may take a couple of days for your domain registration to go through, while you are on the free trial, you are limited to creating 10 users.
