Earlier, we were talking about the occasional need to leave an e-mail address when you sign up for some Internet service. My pal Josh Jones has set up something which may help you in some situations…
It's www.spam.la, which is a completely spammable domain. Use anything@spam.la as a fake e-mail address. "Anything" can be anything. You can enter fred@spam.la or GeorgeBush@spam.la or popeye@spam.la or any name you like. Any replies don't go to you. They go to a message board Josh has set up at http://www.spam.la.
This won't help you with sites that want to send you a confirmation e-mail to validate the address you leave, but it may be of value in some situations. And if you get a longing to read junk mail, there's plenty there to enjoy.
