I can’t speak for everyone else who has a vested interest in CIS but I for one wasn't contacted until right at the last minute and when I tried to broker some kind of amiable and mutually pleasing agreement between the two groups interested in reformation under the CIS name I was met with hostility, especially from Zocane who as far as I'm aware is yet to concede that anyone other than KasMage and himself have any legitimate right to claim interest in CIS' well being.
Furthermore it's not a matter of courtesy, it’s common sense. There were people far more powerful than the likes of KasMage and Zocane in shaping CIS' history and to exclude them from negotiations of such a nature is insensitive, conceited and frankly stupid. The fact that you had to suggest for them to do so, if anything, illustrates petulance and immaturity on their behalf.
