Enter your URL in the box and click "check URL"

Click "Easy Submit" on the left

Click "Easy submit Step 1 of 3"

Fill in the form (I use a yahoo e-mail address, becaus some do mail you for verification)

Click the next button to add your site. A couple of them require you to add more information, so follow the on-screen instructions.

This free submission will add your site to 10 search engines, one of them being yahoo.

True, I have lots more to add later so keep your eyes peeled.

Some of the ones later, in with the free ones, do ask for payment. But I skip those.
