How di I change my username?
At the moment my username is my email address.
As clearly stated :
To login (username is your e-mail address now)
You need to use your email/password to loging, but the shown username (as you can see in your profile and at any post from you) is tom.mackay
I understand your post.
But it does not explain how to change my/username or display name whichever appears when I post.
Are they the same?
You can change the displayed name in your profile settings.
checking change!
