I am an admin of the group. I would rather not be, but since I created the group, I cannot remove myself as an admin. My idea - delete the group and make another? More then half the group is made up of inactive MR members anyway.
Apparently Steam allows users to leave the groups they created now, so I left the group. I dunno if Shockslayer made a new group or not, but Palmer and Zero are the admins of the MR group.
