Is it time to say 'Regards' to email sign-offs? Debate rages over whether we still need polite farewell in online exchanges |

I saw this piece in the Sydney Morning Herald and in Salon. Well if I e mail a friend I never sign off with anything at all. If I am sending an office type e mail, to a person in a company or whatever, I use Regards if I'm happy and nothing if  ain't happy.
