Correct me if I'm wrong, the whole "40 minutes for each transfer" thing is because Ukyo doesn't want to close weexchange.
But seriously @Ukyo, you really think people are going to use weexchange again in the future even if you fix the withdraw issue?
He seems to live in that illusion. There are quite a few good solutions offered here. He should take every measure to fix this problem and after that try to re-launch WeEx, or w/e. Keeping WeEx on running should be of lower priority right now, even in the interest of WeEx.
