I did found this online sandbox checking tool http://www.searchenginegenie.com/sandbox-checker.htm I thought that someone who would like to check that his or her site is in sandbox or not would find it useful for the reference.

If you have some more tools then please do add them.

Sorry to show my lameness, but could you please explain what a sandbox is?

Thank you,
Cy

It has always been a controversial subject so if I say something here then 1000's of people will start raising this and that questions.

I have found this one for you : http://en.wikipedia.org/wiki/Sandbox_Effect

Now atleast people can say that bah wiki is wrong on this and that.
