If you ever need to remove a user, head to ‘User List’ on the ‘Settings’ page, and the click the ‘Remove’ button
next to the user you want to remove.
A pop up will then appear asking if you’d definitely like to remove the user you’ve selected.
If you’re happy to, click ‘I’m sure, delete this user’ and they’ll be removed forever.
If not, click ‘Cancel’ or ‘X’ (this can be found in the top right corner of the pop up).
