Depends how you're doing things. If you're cooking completely separately I recommend keeping pots, pans and cupboard food in your room/a locked cupboard. It sounds a bit anal, but no one will mind and it stops someone pinching it while drunk (which will happen). It just prevents fights/arguments and you can always loan it from your room if they're desperate/you're feeling kind.
In my second year me and a few friends had a house and decided to opt for a cooking rota. Generally this worked well and I would recommend it, but three of us were alright cooks, the other was a godawful cook and it got to the stage where I would end up making myself something more edible. We later cut him out and had him do his own shopping/cooking and it worked fine. So yeah, give it a go, but make sure that everyone is going to cook things people like rather than terrible curries that no one enjoys.
Beyond that just try not to set anyone/anything on fire.
