This is spinoff from the 'smoke' thread. One poster said she covers her behind by emailing parents. I also like to use email because it allows me to keep close contact with parents, do it at my own convenience, and have a copy of our conversations. A few teachers and principals I know like this form of communication as well, but on the other side, our union and some principals recomment against it (although I don't quite see what could go wrong if you are careful to keep your messages professional). What's your opinion and what could the possible cons be against using email?
