How do I get a token?

Super bummed because I just got an email giving me a Docker for Mac Beta 9 update and I thought, oh, this is neat, and promptly uninstalled my current version of Docker. Then once I downloaded the beta, I realized you need an invite code. Would have been nice to have been told this in the email!

Obviously I can reinstall the current version of Docker, but it would have been nice to play with the Beta. Is there any reason it is invite only at this point?

+1 on this. Exactly the same scenario and pretty annoyed that it told me to remove Virtualbox before it asked for the token.

So apparently (h/t to @frenchben via twitter) I did get an invite token a few days ago, but it must have been captured by my spam filter. Check there!
