They never said anything with regards to contact information.
Sounds like the consensus is that nobody really knows why they need that information. Perhaps a special campaign?
I don’t keep up with Jw stuff but let’s hope it’s for good intentions.
We made it very clear to them a few years ago that we wanted nothing to do with the JW’s anymore. (They wanted to take our daughter to meetings while our son was in NICU) We made it very clear that, while we appreciate all that they were doing, we didn’t want our daughter exposed to that environment.
