Yahoo SE as well as the MSN Sandboxes
 

Today everyone identifies the sandboxes as an instrument to convey various information and instructions that the users must follow. But, unlikely the search engines Yahoo and MSN lack this particular feature in their account. Is it true? Or is it just a rumor? Launching new product is not easy on the web world. To top it all you have to market it well to reach your targeted customer. I am not sure whether yahoo or MSN are actually using this sandbox program or not. I want to know how far it helps in the search engine promotion or is it fake.

Your view point is special,I appreciate it.
