Collaboration is believed as an effort to balance between competition and sharing which will take many benefits to create a strategic advantage between collaborating parties. With the growth of the Internet and ICT, the conducting of collaboration through WWW platform will transcend the barriers of time and horizon. It will also expand the spectrum of collaboration.  Member selection is an important decision to be made when creating a virtual collaboration. A project manager should consider social dimensional factors early in the member creation process. This social dimension variable is critical to the effectiveness of the performance of the collaboration. This paper analyzes two social variables which are trust and self-regulation tactic as basic requirements in member recruitment of a virtual collaboration. Trust is widely argued as a predictor of collaboration performance because of the lack of face-to-face meetings. As trust in a virtual collaboration needs to be established quickly, interest in the task as individual feelings and perceptions of the value or relevance of the task are arguably key factors. A high degree of task interest will lead to motivation and self-regulation which is important when collaborating independently and virtually, and to create a sustainability.
