I should say that the google group is not used that much. Most boulder
chinese are using the email list which you can find at:
http://www.colorado.edu/studentgroups/cu-cssa/
as "email list Registration".
In Boulder, most Chinese people live in the school house, called the
"family housing" including Newton Court/ Smiley Court/ Athens Court
and etc. The monthly rent of a 2 bed room is about 900$. There is
other apartments in Boulder available in Boulder area such as
"creekside" which is facing NIST. The price is about the same maybe
slightly less. Usually 1month rent is required before you move in as
security deposit.
