We asked the bureaus to establish a "pre-Katrina credit score" so that Katrina victims aren't hit with another hurricane, Hurrican Bad Credit. But they've all refused (since we put the release out this morning, Trans Union joined Equifax and Experian in rejecting our request).
On the other hand, the leading credit score developer, Fair Isaac Company (FICO), has been working with us to attempt to find a solution. Previous blog.
