Same date for me. It's really a pity that nothing has been released for so long. Restricting open signups is fine, but the fact that people request invites means that there is definite support for the product, and those people are clearly willing to put up with a few bugs. These are exactly the kind of people who add fantastic value to the product, since you're essentially getting free product testing from people who are already passionate about the product.
