Definitely
I will gladly set one up. It will be private and I suggest that everyone reads directly from the group (sign up with no email) as the email load will be heavy.
I don't want it to turn into a let's bash Natalee, Natalee's Family, or Natalee's friends type thing. Anyone that has been following the case know that "things happen" and the bad people in this case are the ones who are refusing to talk to the people or who will not give the police any straight stories.
