Sign up for an account on the right, just enter a username, e-mail address, and password. Then click on the Make a list link or Make a gift link and make a list of anything you want, i.e. things you want, things you don't want, things you need to do, people you like, people you hate, favorite movies, foods, etc. You can even include links in the lists by just typing the site name, for example www.cnn.com
Once you've made your list click on the Share/Save button under your list to share your list via e-mail or on 50+ social networking sites like Facebook, Twitter, etc. You can opt to allow people to comment on your list as well so make a list of which movies are playing this weekend and let your friends help you decide which to see.
