I think we already have what we need:
A group of people working to change the practices to prevent more victims
A group of people working to support and help survivors
Of course some / many of the people may work for both ends or they may work for just one as they feel they can.
I think creating more and more organisations is not the way to go. Everything is already in place and there are lots of good people putting ni a lot of effort and hard work.
All we need to do is ensure that individuals don't try to derail or redirect things for their own purposes (or that of the WTS) and I'm sure there will be no end to what can eb achieved.
