I've not yet set up the project for preorder (I might look into that at some point when I have some spare time), but followers should get notified when it updates, including at release!
We're still on schedule! We've just completed the development edit and are coming up to the end of the second art round. The major steps left are copyediting (which we've just begun) and layout (which has been ongoing for a while). Obviously I can't give a firm date for release, but we're getting closer!
