yes I read through those links, and there it stands regarding the 2nd year membership: "This pricing is available for first time membership only and limited to eligible education customers" - so I read it as I have to pay full price since I have now graduated. Yet in my monthly mail from Adobe they say that I will only pay the reduced price unless I cancel the plan in this twelfth month. If they're not going to automatically take full price, how can I make them aware of that I'm not a student anymore?
Well, Adobe also says a couple other things about student discount eligibility – like any documents dated within the past six months are accepted, or simply if you have a school-issued email address (like ending in ".edu")...
So you may be OK to renew at the discounted price depending on how recently you are talking about.
