Well for once . .
there are good arguments on both sides of the issue. Interesting.
However, I must admit that I believe leaving one's mail on the Internet is a daft idea to begin with.
Need to contact someone ? Ugh, start the computer, dial in, open mail, get contact details, grab the phone. Need to find that mail you got in 2002 from that friend whose name you don't remember ? Double ugh, need to boot up, dial in, open mail and search mail box, possibly the least efficient way of doing things.
And on top of that, you're at risk of losing all your data if you don't have a backup.
These people have obviously not lost enough data yet. I'm almost hoping that Orange will not be able to restore them mailboxes. These users need the lesson.
Once upon a time computers were expensive, disc space was worth gold and nobody could properly back up data at home. Nowadays a PC is $500, comes with a DVD burner and the media is worth peanuts.
There is little excuse to leave mail on the Internet anymore, and none at all if you only read it from home.
