I used Wufoo to reduce the need for multiple "paper" forms. I worked at a school where multiple forms went out each year to parents to enroll/re-enroll their child for the next school year -- anything from parent information to signing up for lunch. By using Wufoo's form generator, we were able to reduce the number of forms sent home to parents by 90%. The best part about using Wufoo was that all the information parents entered through our Wufoo forms was downloaded to a very usable excel file which meant no more computer entry of information for our families. This reduced hours and hours of monotonous computer entry of family information (can you imagine all those phone numbers?) and dramatically reduced the number of entry mistakes. The side benefit was our huge reduction in paper usage.
