Autodesk is encouraging you to use the Autodesk Community (formerly know as forums, discussion groups, newsgroups, etc.) to get answers to your questions by setting up a special day where Autodesk people will attend and be responsive. I don’t know if this includes responding to people’s concerns over Autodesk ending the sale of perpetual licenses, but it’s worth a try anyway. The forum for discussing that particular issue is somewhat hidden. It doesn’t appear among the list of forums, so you would only know it existed if you happened to pick on the Installation and Licensing link and had a look at the header to see the Perpetual License Changes link. But now you know it’s there, you can go and ask your questions. Meaningful answers are not guaranteed.
Here is the announcement. When is this event, exactly?
Join us at our first “Big Bang” Answer Day online event on Wednesday, May 18th from 6:00am to 6:00pm Pacific Time.
Pacific Time is currently UTC (GMT) -7 hours, so for people outside North America, that means UTC 1 PM Wednesday 18 May to 1 AM Thursday 19 May. To calculate the times in your own location, I suggest using the very handy timeanddate.com site or thetimenow.com.
