On a related topic, I also heard that when you make your e-mail address book it goes first in numerical, then alphabetical order. If you make up an e-mail address that consists solely of zeros i.e. 0@00.com and put their first AND last name as 0 (zero) too, this can stop potential viruses sending their nastiness on to all your e-mail contacts (it will list the 0@00 first as it's numerical and the virus is supposed to stop there).

I don't know how true it is though. Perhaps someone else has heard this and can either verify it or rubbish it?
