I feel it would be better to wait until Thursday noon. Let's give them genuine opportunity to convince us that they are straight and that all is well. I really think they should have that opportunity. If they fail to make use of it, then for sure, the gloves are off. If they are straight (which I hope) then an avalanche of civil and criminal cases directed at them may make it a lot harder for them to just get on with it and solve it. So I recommend let's not be too hasty.
I agree...as much as anything because I'm busy with other things at the moment. This will allow some time to formulate the most effective plan if Paymium fails to come through. Your Thursday deadline seems about right.
