If you have a smart phone and a Steam account check out the Steam App on your systems market place. I just got this update today saying it's open to all users.
Now you might ask what can you do on the Steam App. Well you can chat with your friends on Steam were every you are, even if your signed in via your PC. You can check out peoples profiles, groups, game news, reviews, buy games, and even stay up to date with sales. As an added plus everything you send or get while chatting goes to your PC synonymously so long as your signed in there.
Now this is still in beta and there are a few minor bugs, but it's still a good way to stay connected when your not at home or you just don't want your PC on all day to get messages.
Have a good day,
