How do I publish a script?
While scripts are saved automatically to your temporary internet files, publishing a script (thereby generating a URL) is something that can only be done with a website account.
For moderation and data protection reasons, the creation of accounts is heavily restricted. Only teachers of registered schools, BBC micro:bit partners and Code Club volunteers are eligible to receive an access code to make an account.
However, all other website functions, activities and editors are available to anyone and everyone without an account.
