||The Fight Against Spam, Part 1|
A friend of mine runs this site and it's a great way to avoid spam - disposable email addresses that forward a certain number of messages to you and then every message after that gets "eaten!" Great for when you need to give someone or some site you don't trust your email address, and best of all it's FREE!
He's a big Linux user, and I'ms till trying to convince him of the wonder os of Mac OS X, though. ;~)
