I got the same email too a couple hours ago, have replied by email and signed up as I dont intend leaving anytime soon so a new contract is not a problem for me.
I also suggested they carry out a survey of VIPers to get a broader range of opinions other than all from forums.
No complaints from me on VM's handling of this and fingers crossed the revamp really will be worth the wait.

Edit: Just got the same reply back .. Out of office on training next week ... may need to phone instead if things arent done Monday
