Change profile information and avatar in the forum

When I change my profile information (avatar, e-mail, name etc.) on raywenderlich.com, it is not mirrored on this forum. My profile photo change in gravatar.com does not seem to have any effect here either.

How can I change my profile information (avatar, e-mail, name etc.) on this forum?

@ertugrul Thank you for the heads up. I will forward this to the engineering team.
