PING!
Get ready to be filled up with the messages from all possible chats that are usually used for remote work (e.g. Slack, Twist, Flock, etc). If you feel overwhelmed or simply don't have the patience to follow it all, just mute the ones you currently don't need, ask your colleagues to call you for something urgent. As well as, some people do prefer to discuss important things "in person", so video call'em.
