when my sister enters her password and username and clicks "connect" she is returned to the log in screen. She has double checked the information and click the link in the confirmation email.

Hello. I created a new account with a new e-mail address. I have an existing account with a different e-mai.l address and I would like that one deleted. The email address I would like is rdfjr@ptd.net. The username is Rob. Thanks.

To delete your her account, go to account settings then enter username/password. Then it will ask u if u really want to delete your account. Say yes, and then press enter. Hope this hels.
