100 "Real" Registered Users

New social community website needs help getting started. Prior to beginning any marketing campaigns of my own, I need to get a minimum 100 registered users on the site. The site address is [login to view URL] Prior to receiving payment, at least 100 visitors that you invite to the site must remain active and post an update at least once every two days for two weeks. These MUST be real users and not the same person creating 100 accounts. This can be verified (even if you are using a proxy). PLEASE NOTE: my marketing options are still open. If you do well at this it could develop into a regular or periodic project for you. ALSO: Registered users must reside in the US. Anyone can register but only US registrants will count toward the 100.
