Wow sounds like the signing was a big deal, hope it makes you some coin.
The elders treated it like a big deal too, just shows that despite good intentions they are truly not qualified for their responsibility. Thats sad about your sister and your kids so sad i bet the elders would cringe if they ever become exjws and realise what they had done. At the moment they feel they are doing gods will, very frustrating.
Hope all works out and your sister comes round before too much time is lost.
Cheers
