Imagine it this way...
I go to open my account in my web browser so I can go delete all the mails (it's easier to delete them at the web site than it is to delete them using the Hotmail support in outlook express). There are a few thousand mails, so it's gonna take like 5 or 6 minutes to delete them all. By the time I'm done deleting them all, I have 50 or 60 new emails in my inbox. That's when I stopped using the account. I do more deleting than actually reading the mail in it. Everyone who used to email me at that address now knows my newer email addies, so it's all good.
