Okay, my bad, I was under the impression that before just recently, the only way to get new seats was through the suite on the website that included Soft.
(should have read through the old FAQ, and there was also a recent discussion that I should have recalled but didn't)
But I think my impression was from sifting through things and finding the following..
I agree the updated FAQ (May) should contain the information that you can purchase new seats of the bundle - I'll see if I can get that added. Please don't refer to the original FAQ because it contains information that has since changed (for the better).
And for the latter..
Anyone can buy extra seats of the Maya + Softimage bundle until Feb 1, 2016
Which was in response to a comment about it being only available to existing customers.
So apologies for my confusion, while perhaps still being confused about the 'Anyone' part,
would frankly be unfortunate if it only meant 'any(existing customer)one', and would be great if that could be clarified.
