How many times have you’ve been working on a document – shaping and tweaking the words just perfectly, only to become a victim of a power outage or a wonky computer that freezes in its tracks if you have more than one program open? Hours of work gone in an instant. Save early and often. And then back it up! As simplistic as it sounds, many neglect to put that into practice.
Furthermore, for complete and accurate documentation, anytime you send an important e-mail to your professor or post a discussion item in the classroom, send a copy to yourself at an alternate e-mail address, such as an Hotmail or Yahoo account. This will ensure that you’ll have a complete set of records in case something happens to the school’s program server or network. This is critical for assignments due by a certain time.
