"When my students knew that they'd be sending e-mail to students in South Africa, Japan and England as part of the Global Water Sample Project at P.S. 22, I had a problem I've never encountered before - they were writing too much!  They felt that people from other countries would be reading their words and they wanted to communicate extensively with them.  They were also much more careful about grammar and spelling, since many of our partners were not native English speakers."
