The Oasis program I think is generally used when a card has been closed, and an account defaulted on, but Kudos on getting into a hardship program and getting straight with them. I did this many years ago with Citibank.
I wasn't even aware of Fort Parker

sounds interesting - I have read alot about Quanah Parker and the entire family over the years. I actually have a TX Cattleman's book from the late 1800's that has a very good account of the tragedy.
