When I see "Book early to avoid disappointment" I always wonder "Yours or Ours ?" but last year Tech-Ed sold out 6 weeks before the conference. I remember asking the organizer if that meant it was too cheap or the venue was too small :-)
I had a message on Friday
This is just an FYI, but with Super Early Bird ending on 31st July we are in great shape.The registration trend for this year is that overall the numbers are double compared to the same time last year.
If you want to go to now would be a great time to head over to the registration site for Tech-ed IT forum (or Tech-ed Developer). There were some disappointed people last year, and it looks like there will be more this year.
