Where can I change my username?Watch
"The Student Room no longer enables members to change their usernames, as this not only causes unnecessary work for the Community Team, but it can also lead to confusion on the site. If you have started an account and wish to have a different username, then you will have to create a new account.
In exceptional circumstances, the TSR moderation team may consider changing a member’s username. This is usually only done when a members username is easily identifiable with them in real life, such as their initials and date of birth, surname, or email address. If you think your circumstances could warrant a change of username, then visit the Moderation Queries forum."
