Step by step visual guide:
Having trouble changing your username?
You're unable to select a desired username.
Some usernames may be unavailable for use because a) this username is in use by another user or b) this username is in use by a deactivated account. If you have a registered trademark that is in use by an account that is potentially inactive or in violation of trademark policy, please contact us by email email@example.com .
Desired username is used by your other 500px account.
If you're trying to move a username from one of your accounts to another account, you can do this yourself.1. First, log in to the account that currently has the desired username.
2. Then, change the username to something else (any other available username will work or to be fair add “_old”). This will immediately free up the username for use by other accounts.
3. Log in to your primary account and change your username to the desired username.
Please note: Once you’ve changed your username, it returns to general circulation and may be selected by another account. Also, please note that deactivating an account will not free up the username.Need more help? Email firstname.lastname@example.org or tweet @500px_help
