If you have ever been irritated by a news article link that drops you at a 'free' registration page, then definitely check out bugmenot. It is essentially an online free index of usernames and passwords to sites that require 'free' registration. No more typing garbage into a registration forms and trying to figure out whether to click the checkbox labelled [ ] Shall we not never not (not) send you spam and sell your email address? Just use bugmenot to get a currently working, updated when needed, username and password pair to give you access. If you happen to use Mozilla or FireFox, you can get a bugmenot extension to retrieve login information for a site with a right-click. The extension even auto-fills the form fields and submits. There is also one for IE, and also a barebones bookmarklet.
