How do I report someone who sent an email from my address at yahoo?

And how did they do it. I've changed my password but someone was able to send everyone on my contact list an email about a website.

How do I report someone who sent an email from my address at yahoo?
That sounds like somebody hijacked your address book, several sites are known for doing that after you signed up with them. Reporting that to Yahoo won't help, you need to do a spyware scan of your system to delete possible keyloggers or other malware. If you don't have a good program, get the freeware tool "hijackthis", it quickly scans your computer to find settings that may have been changed by spyware, malware or other unwanted programs. HijackThis creates a report, or log file, with the results of the scan. Check the "overview, FAQ and quick start guide" buttons in the top bar to find out how this tool works.

Then google for "hijackthis forum", click on one of the many links and follow the prompts. Those forums have volunteers who help you to analyze your hijackthis log and get rid of the malware on your computer. Below are a couple of links to such forums:
