It's not possible to remove a profile. We can deactivate your account. Deactivating your account will prevent you from posting, as well as seeing read/unread markers or using 'my chow' or using any other features that require login. It won't remove all of your previous posts. Deactivating your account also won't hide any information in your profile ( http://www.chow.com/profile/ ).
If you want your account deactivated, send an email to email@example.com, and we'll do that for you. You may want to remove any personal information / answers from your profile before we deactivate your account, as you'll be unable to update it after.
