Looks like Alpine is restricted to a set of testers for now.

I look forward to this going public. I was once a long time Pine user, but moved to mutt quite some time ago. The reason wasn't even good - color worked on mutt, and I couldn't get it to work on Pine, or it was supported on Pine at the time.

I look forward to trying it out, mutt is good, but not perfect. And unlike many of my former mutt and pine friends who have jumped to Thunderbird, I just can't feel productive in a GUI mail client.
