A "submit" is a correctly filled form and not just a click on submit btw... so its users that go from here:
http://enter.mofosnetwork.com/signup...hed=1&strack=1
to here:
https://www.securpayment.com/signup/...7cfc0904a17100
... successfully. It doesnt count errors made on the first page, like invalid user/pass combninations or clicking on a join option thats not available for the payment type.
