First of all… do you want an invite? Ask for it in this link, it looks pretty official to me. I have found some twitter accounts to follow, but I could not say they are authentic. Anyway, try the link I included, maybe you will get lucky!
Second… help us answering the poll (right side), it will be very interesting to see how willing is the people to change something like their email. There is still a lot to ask you, but this is the first question of all.
Have a great Week!
