>Is it possible to email allthe CIS memebrs on UT to forewarn them what is happening and to advise them that the way forwrd is to use another accountand to complain loudly to CIS.

Not all of them are using the mailing list interface so it might not be a factor for them. However, it might be useful to have this limitation removed.

>I'm surprised given the laws of free speech and interference with communication that CIS is allowed to get away with arbitrarily deciding who can and can not recieved what mail.

Yes, correct. I remember having a situation where I was in need to send an urgent mail to a CIS member and I had to retry all week long until there was a place for me to get that email.
