How to delete account?

...Hi sincere, All of the others have given perfect answers. I would like to know why you are leaving RightMedia? Is there a problem with the site or just your own peron choice of not wanting to be there. Please let us know if we should not be involved for some particular reason. Thank you for taking the time to respond. I do appreciate it. Take care.

Just contact them via support ticket or something like that. Ask them to delete your account.

you don't need do anything, most of the sites will deleate your accounts after long time without login.
