Question about hotmail

I share a computer with a roommate whom I trust.

We both have use hotmail, but everytime we each log in, when have sign in with a different address and enter our own email address.

I've seen on some people's computer where hotmail lists a mutiple email address, all you have to do is enter your password. Does anybody know how to do this?

Thanks

I don't use Hotmail, but as a suggestion, wouldn't it be simpler to use separate Windows accounts so that each of you can keep your own files and settings? This would include browser information including email accounts, passwords, etc.
