Zrevnur: IIRC it enables two buttons. One of them is likely for GOG.
No idea about that, probably because I already have the main notification setting enabled. I just have the Partners setting and the Wishlists setting both disabled (not selected).
So all that changes for me when I grab a free game from GOG is the Partners setting, which gets immediately deselected by TheDcoder's script.
The only reason I have the Wishlists setting deselected, is because I was getting too many emails from GOG, no doubt because I have so many items on my wishlist.
I do want notifications about free games, great redeemable discounts and new releases.
I don't need to be told about something I know I just bought or about games they think I should get, that often includes many games I already have at GOG.
GOG should recognize I am a great supportive customer, and not pester me with unnecessary things. I know what I want and have bought.
