Siannah: Since the fine folks of GOG stated in the email:
"you're free to add the game to your account or share it with a friend" ... I'll jump right in before it expires unused on January 13th.
ZFR: Nobody's saying you shouldn't share the code, but please don't post them publicly like this. You're littering the forums and attracting leechers, or the code could be grabbed by a bot.
If you have a code that's going to expire then by all means give it away. But do so by saying that you have one, and then sending the code by private chat to the recipient.
Guys, take the gift as it is.
I'm happy to give away it, but anything else is too much effort for me.
This post, to replay to a complain about how i divulged my game code, is too much effort.
So, if there is a specific rule not to do so, I'll follow it, and I'll no bother anymore giving my surplus codes.
If there is no such rule....
