not sure how this works and if you still need to be in the steam cloud in order for this to work. I expect that IW will not let this go on for much longer.. although I do not see the harm in allowing this.. there is no reason for them to not allow it. If you need steam to make this work I cannot imagine that Steam will let this go on.
But good for them and hopefully most PC gamers will take advantage of this because IW really needs to learn a lesson from this one way or another.
its seriously distroyed their pc sales not having dedicated servers , i know a fair few clans and friends that wont buy it because of this , it just makes no sense.a game that relies on keeping its multiplayer community happy,not doing it too well
