I received the beta invitation last week but was busy and put the email in my "to be read later" folder. After seeing this thread, I retrieved it and tried to register. Lo and behold, this is what I got:

Thanks for your interest in the Beta Test for the new eService Online.

We reached our goal for the number of participants we needed.

Watch for the new eService Online to be launched soon!

Lessons learned: 1) read my emails on a timely basis, and 2) read Flyertalk more regularly.
