I used to use Outlook Express till it vanished in Windows 7
It didn't vanish and I'm using it now. All that happened is that under Vista
Microsoft moved it to be part of Windows Live and that's still the case
today in Windows 7.

It's much the same as ever (albeit sporting a Ribbon now), with the sole
exception that it no longer puts a "" in front of quoted text. I guess
whoever was responsible for that bit of code was a top-poster! :P
