In order to use Google services (like Google Calendar, Google Docs, Google+ etc.) you need to be logged in. But did you know that you can continue to use services using any email address?Yes, it’s true! You can use any email address (Yahoo, Live etc.). Or better still you can use your company’s email address (providing there are no policy/regulations for using your email account). This way, you can look professional and still use Google’s services.
