Hi 

I'm looking into Siteforce, I read this post - Siteforce - Pilot in Spring'11 

included [If you are not already enrolled in the pilot and wish to be, then please contact your Account Executive or Customer Success Manager.]

I want to use trial(pilot program) of Siteforce. 

but, I don't know how contact my Account Executive or Customer Success Manager. 

and I can't find Siteforce tab in my saleforce.com Home. 

How can I be enrolled Siteforce Pilot program? 

any reply would be appreciated
