Can anyone tell me how to get the forum icon on the paradox forums that is supposed to be included in the Deluxe / First Colony edition? According to the paradox site I'm supposed to supply them with some code (for non-steam products), but I don't know where to find said code.

On the game-page in your library click "More", one option is "Serial keys". You can use these keys under "Redeem code" on the paradox website.

I'm not seeing the option "Serial key". The only options under "More" are:

Overview
Settings
Backup and Goodies
Manage Installation
View Forum
View Support
View Store Page

None of the sub menus seem to have it either, unless I'm blind.

Try the library on the actual website, not in Galaxy.

Aha! Thanks, that worked.
