You may remember the announcement that the waitlist had been closed.
So that customers (potential attendees) are served best, about 1/5 of the people on the wait list should be cleared today. The open spots are being cleared for a number of reasons including cancellations. If you signed-up early for the waitlist, you may receive an email very soon releasing a spot for you!
Also, more spaces should be made available as we get closer to MMS 2012 as the list of attendees is sifted through to make sure actual customers have availability to attend.
Stay tuned for more information.
