Classics is correct. I received the following notice:
IMPORTANT NOTICE ABOUT INKTOMI SEARCH SUBMIT:
Dear Inktomi Search Submit Customer,
Yahoo! Search has transitioned to its own search technology and is preparing to launch a new inclusion program. As a bonus for Search Submit customers, Yahoo! Search is providing a free trial of Yahoo! traffic that will end on April 15, 2004. During and after the free trial of Yahoo! traffic, you will continue to receive your usual traffic from the rest of the Inktomi distribution network.
When the new inclusion program launches, Search Submit customers will have the option of joining the new program for ongoing participation in Yahoo! Search results.
