Hi! 
I am working on a game and I would like to upload a free demo version of my game on GameJolt and I will be getting some small amount of money from ads so I will send an Email to Epic to notify them about it.
I would like to know what happens when I release my game on Steam as a paid game, do I need to send an Email again?
My second question is : What should I put under “unique product identifier(s)” for now when I’m releasing it on Gamejolt?
Thank you!
Thank you!
