i was wondering about this. i read about it in the announcements topic and i'm curious if it will happen. i hope not. because i don't want to be forced to login via steam. this is private. if this is to stop pirates and tricking them into buying the game for mods it's alright. but you could ask everyone to send a pm or mail with proof you own the game and dlc. for example via a screenshot. if you don't do this your account may be blocked from downloading the attachments or will remove your posting privileges.
