Starting a new xbox site

Hey there,
I'm working on starting a new xbox related gaming community and news oriented site http://xboxgrid.com

I plan on releasing a more involved content system, to provide users with news, reviews, and other goodies, but until then, I'd like to start building up the community.

How would one go about getting users to register on a site that has no active users?

try hiring paid posters to kick start the site. You could also try to register, rate and review it by others.
