To me, it seems that shadowbox is right. I'll contact them for sure, but when they say "when the user is no longer a student[...]" I think that the seems to imply that, while I am a student, I can use it commercially. The clause is once I'm not a student, not once I start using it commercially. I'll call for sure.
Meh :/ Should've done that in the first place. Can be closed if no one else has anything interesting to add.
