Vengeance is a pretty good name. Why change it?
Is"Harry Legg" your real name? That can't be easy.
I'm surprised you don't go with Harold.

How can I change my username?
If you would like to change your username but keep your current account
Point your cursor top right of your Chess.com homepage where it shows
HOME and a drop down menu will appear.
Click where it shows Account. Once that page opens click on Edit Profile
From there you can now change your own username.
Alternatively clicking on your own homepage avatar will take you to
the Edit Profile page.
Please choose carefully as members can only change their username once :)
Please note that usernames are a minimum of 3 characters and a
maximum of 20 and you cannot have any spaces or dots in the name, nor
any special characters like ^ & * ! " £ $ % ( ) + = ? / \ |
It can be either one whole word, or use a dash (-) or underscore (_) as a separator.
This thread reports the same problem you did and
suggests contact a moderator (sending in a support ticket)

Recently, I tried to change my username, however, when I clicked on the option it said: "you cannot change your username when logged into live chess."
So, naturally, I logged out from live chess, but the same notificaiton came up again when I tried to change the username. Any advice? I've tried qutting chrome and going back on but it still doesn't work.
Thanks in advance, if this is the wrong place to ask, sorry.
