How do I change my newsletter e-mail address or unsubscribe from newsletters?
Each newsletter contains a link that allows you to change your newsletter e-mail address and manage the rest of your newsletter preferences. If you encounter any difficulties, e-mail us.

How do I suggest an article topic?
You can e-mail us here with suggestions. Please note that we currently have a five-mile-long list of article ideas and that many factors go into deciding what kinds of articles to write.

When can I expect to see my question or topic suggestion published on HowStuffWorks? Can you e-mail me when it's up?
We appreciate our readers' article suggestions. Since we receive hundreds of suggestions per week, we cannot answer every single one and, unfortunately, we are unable to tell readers when we might use their idea in an article or question. Check the site often to see if your topic has been published.

How do I suggest a link?
We appreciate and encourage our readers' link suggestions. In fact, external links provide our readers with a valuable service, an additional source to find out more information on a particular subject. Since we receive hundreds of link suggestions per week, we obviously cannot answer every single one, and, unfortunately, we are unable to add every link suggestion to our articles or questions.

How do I tell you about a correction that you need to make to an article?
Please e-mail us if you have a correction suggestion. Even if it's just a typo on a page or a broken link, we definitely want to hear about it so we can fix it. Unfortunately, we cannot always reply to correction suggestions and we are unable to let you know when we've made the correction.

What is the best search engine to use?
There is a search form in the right-hand corner at the top of every article page that will search the entire HowStuffWorks site for you as well as Google. On the home page, the search form is also in the top corner on the right-hand side.

I am a student and would like to use one of your articles in my research project. Can I have your permission to do so?
We are happy to grant permission to use our material for noncommercial, nonprofit, educational purposes. We ask that you not alter the images or content from the way they appear on our site, and that you cite HowStuffWorks as your source.

Can you provide me with the date an article was written to use in my project bibliography?
All of our articles have a "Page Tools" section at the bottom of each page. If you click on "Cite This," you will see a citation for the article, including the author and publish date.

I would like to use your graphics or animations in my school presentation. Is there a way I can copy them from your site? If not, can you send me the files I need?
The animations on HowStuffWorks are Flash files which cannot be copied the way .gif and .jpg images can. Due to overwhelming requests for animations and the time constraints of our Graphics Department, we are currently unable to send our readers our Flash files.

I would like to use your content for business purposes. Can I have your permission to do so?
If you are not a student, teacher or educational facility, please e-mail our Business Department to discuss the use of HowStuffWorks content.

Why are your contests not open to international readers?

Non-English speakers would also love your material. Are you planning to publish HowStuffWorks in other languages?
We receive quite a few requests from our international readers asking us to translate site contents into languages other than English. Because of this, our business team is currently considering options.
