Gmail Tip

I've been reading Google Hacks 3rd Edition (by Rael Dornfest, Paul Bausch, and Tara Calishain) and learned this handy tip for Gmail.

If you are trying to enter site where you have to register your email but don't want to be deluged with emails and newsletters, simply use your gmail account and append a special prefix ending in a plus sign in front. For example, to register for the Washington Post, enter washpo+youremail@gmail.com. The email address will work as normal, but then you could set up a filter to either delete or track any email that you get from the Washington Post.

You could also use this feature to see who is trading or selling your email address to others.
