Dev.s, why don't you reply to us? Do you listen to our ideas? Our problems? The only change I've noticed recently is it's Christmas. For me, it has been loading more frequently recently, and I thank you for that (if you in fact did anything to influence it), but could you give us some feedback?
I might like the option to reject newcomers... I keep accidently getting more people, and I don't want them! Also, maybe you should add skills (or resources) to them to sweeten the deal. Like, "Hey man, let me in... I have fuel." "How much?" "A bottle" "Not enough." *achievement: reject survivor*
