Hello All, I believe it was mentioned previously, but the link for the CTL Decisions may have gone unoticed by some;
Both the CTL Decision Sheets and the OSM Decision Sheets are available online at: <http://www.cbscheme.org/ct/decisions.htm> At this same location, there is also a description of the CTL and its operational procedures; they may help to clarify some of the questions raised in this forum.
