Is this chase late payment worth pursuing?

[Viper786]

Back when I was in high school in 2005, my sister added me as an authorized user to her credit card. She shut down this account in november of 2009, but according to my credit report, it is showing a 30 day late payment in October of 2007. From what i've been reading, that may not be affecting my credit score much, but I would still like to have that removed from my reports. 

How do I go about removing my name as an authorized user from an account that's been shut down and reporting one 30 day late payment. Is that even possible?

I think either party can GW Chase & ask for the removal.  I'd go for it, Chase has been very forgiving lately.

What is the best way to GW chase? I currently have an open account with them which is about a year old and I have no late payments or anything on my account. I am hoping that works in my favor when I GW them

I sent my GW letter to the address on my CR.  I asked them to remove 2 late TLs and instead they removed the entire TL.
