I found a yahoo group for use with the "goalsystem" (also the name of the group) in CiC. A memebr, Thomas Whitten, wrote some insantity rules to add on to the rules. My membership is pending so I cannot access the file section yet.
There was a bit of chatter this time last year regarding Cthulhu type adventures. I've also checked the S2 group (supersystem 2) and there was also a bit of talk.
One I get int the group I will also start combining some of the notes from both groups and post them here.
