hello colin.
here is where you can submit to yahoo.

right now, a lot of my traffic is coming from yahoo, with no paid listings. and waiting to see what msn does when their listings when things stabilize there.
yahoo traffic for me converts a lot better than when i had mostly google traffic. about 30% better, i would say.
right now, google's results seem not to be really that fresh, the same goes for yahoo. msn, on the other hand is listing new stuff in 48 hours or less usually.
as for google and their "sandbox". i think it's a way to force site owners into paying for hits.
keep in mind, right now, there is a search engine war going on and the spiders are real active.
Colin, if you ever want to talk seo, hit me up on icq. 79493698
