SAGE China Linkedin Group?

For SAGE China, now we have a user page on Renren (Biggest social media for students in China), a website(www.sagechina.org) and a blog(sagechina.blogspot.com).
I drafted a blueprint for these stuff from what I know so far. Please give comments,or please correct me.
If we are going to have SAGE China Linkedin group. Here is my plan.
