i introduced it to my prof who does a game art class. a few students have already migrated, but hopefully everyone prototypes their games in construct instead of flash (our class collaborates with programmers for the actual game)
They won't kick you unless they're one of those schools that are tangled with Microsoft... y'know, if the headmaster is receiving some cut from the big Microsoft cake baked at the school, he might remove you forcefully if you ever suggest using some OTHER software....
It's a harmless suggestion, which you may as well try.
If nothing else, start a club which runs at lunchtime or something for people who want to take part. You'll be able to put that you taught an amateur game development class in your spare time on your CV. Handy!
