Manage My Profile
Gravatar profiles power WordPress.com accounts. If you have a WordPress.com account, you have a Gravatar profile. It can be managed either from within your WordPress.com Dashboard at Users -> My Profile , in the Settings tab on the WordPress.com home page, or over at Gravatar. Your WordPress.com login information will allow you to log in at Gravatar.com as well.
The information you enter in your profile will also be a part of what people see when they hover over your Gravatar in comments. It’s a cool way to show off key parts of your profile.
If you forget your password, fear not. That tricky situation can be remedied via a password reset.
The information you put within Gravatar is public. Leave your profile empty (or remove) anything you do not wish to share.
