Looks as if this invite was sent by some of the customer care reps. I was told it was a rehash of the 1/9 meeting which I believe was only for Diamond and Platinum VARs.
From what I saw on the slide deck it was a re-reading of the emails that have been circulated about the changes. I didn't learn anything and as per Sage's new policy only those brave enough to send email to Sage would be able to have any questions answered. No open Q&A.
