If the "kit" tuners become reality, you won't need to have signed up anywhere.

If you hope for pre-manufactured tuners, you can sign up at http://www.eden2.com/empeg/ if you want, but the outlook is looking more and more grim as time goes on.

If the kits come out, it sounds like there will be people who will assemble them for you.

Regardless, if you sign up at the above page, I'll fire off an email when (if) tuner kits become available, so you won't accidentally fall out of the loop. Can't hurt.
