Ever tried to access a site to read an article and found you needed an account? Maybe you are too lazy to create an account for such a small thing, or maybe you don't want to pay for a subscription.
BugMeNot.com was created as a mechanism to quickly bypass the login of web sites that require compulsory registration and/or the collection of personal/demographic information (such as the New York Times).
Some nice people post their username and password and let you use them.
What sites are in the database: www.nytimes.com, www.nypost.com, www.washingtonpost.com, www.chicagotribune.com, www.latimes.com, www.imdb.com and many more.
If you are too lazy to visit BugMeNot.com every time you need a login, you can install a Firefox extension or use a simple bookmarklet.
