Great job with starting this thread!! I was wondering about this myself...
OohTeenyWahine said just about everything I've wanted to say, but when has that ever stopped me from talking anyway??
No one has advertised yet on our Facebook at Mizzou, and a few organizations have already restricted the use of Facebook by their members... leading me to believe that more restrictions will occur before any advertising will.
One house asked all their members to (regardless of what groups they were in or what their profiles said) to remove their affiliations and the group's name from Facebook groups. (Although the women have worked around it... their group no longer states the name and letters of the sorority, but their picture is of an angel... that kind of narrows it down, doesn't it?!) Another group has asked the women to either remove offensive material or remove their affiliations from their profiles...
