For the love of God... don't attempt to pay to get more of your pages listed (PFI)!
If you submit just one of your pages, they will drop all the rest of your site's pages in the hopes you'll than pay for ALL of them to be included.
There is nothing you can do. Just sit back and wait for Inktomi to include the new pages. If the new pages are linked from the existing ones that Ink knows about... than they know about the new ones as well.
Inktomi does not index nearly as much content as Google (at least not till now)... PFI causes them to index even less. Hopefully this will change soon with Yahoo's new focus on search.
