The build isn't public yet. There's no download, no open
server, and no release date — the honest state of things is on the
front page. Leave an address and you'll be told when there is
something you can actually play.
What happens to this
It goes on a list on our own server. Nowhere else.
No account is created and there is no password to set.
It is not sold, shared or handed to a mailing-list company.
One message when there's a build. Not a newsletter.
