Bill,
As others have said, as long as you mention the version of Vegas you are running then you will be fine. The help I have got here over the years has been invaluable, and I regularly find myself coming back, searching the archive and finding the answer to what I am trying to do in the forum. If I cannot find it, someone will invariably suggest an answer. Then, as you grow more proficient, you might take the opportunity to answer questions raised by others. I find little has changed in terms of basic functionality over the past few versions – the biggest change for me has been the UI layout – and frankly some of the changes made seem counter-intuitive, but that is just m,y opinion.
I have been a user since VP9 – when I moved over from Pinnacle Studio – and I have never looked back.
Welcome to the community – it is a vibrant, supportive one – so ask away…
