Make it even more interesting, some doors do make a noise when opened. That way it can't always be a reliable notification. Additionally in some cases, prehaps having the ability to oil door hinges on some doors might also help but not always.

This is DayZ which is a game about survival. Having a constant open world chat is just downright irritating and takes away from the game. If a world chat option is given then at the very least give us the option to turn it off. I don't want to have to sit there and read flamewars, racism, and kids who think they know better.
I really do enjoy that direct is the only communication right now.

It would interesting to have actually, maybe a news window like they have on the main menu for Team Fortress 2. :)
