Since November 2010, new Jagex game accounts are registered with an email address as a username. This email address cannot be changed, although you can change the address we use to contact you. You can also change your character or player name as it appears to other players in our games.
If you registered before November 2010, you should continue to log in using your username, even if you've also registered an email address.
We may contact you occasionally regarding future updates, and to ensure that we are giving you the best possible customer service. You can change your email preferences to opt out of particular services or updates.
