Credit steve carmody / Michigan Radio It’s been more than a week since the registration period for the Flint water settlement closed, but it remains unclear exactly how many people signed up. People affected by the Flint water crisis had until March 29th to register for the $641 million settlement involving the state of Michigan, the city of Flint, McLaren Flint Hospital and Rowe Professional Services. Tens of thousands of registrations poured in by the deadline. One attorney estimates about 50,000 people signed on. But forms post-marked by the deadline are still arriving at the office processing the claims. There’s also another issue.
