Well all great stuff (stuff being a technical term) but I guess my question has gone from how the rankings were done to do they mean anything anyway? Are people actually modifying their behavior to be ranked higher? I wouldn't say this is bad, just interesting. Do people make decisions based on a members ranking? Again there are always those competitive people who want to be number one in everything they do.
As far as rewarding people for time in grade, I have no opinion on that one. From the founders standpoint I would think members who bring other members to the group should rank at the top. Increased membership rewards everyone because it expands the resources available to all members. I vote for those who bring in the most members to be at the top, but only if they are over six feet tall and over 60 years old. Just kidding - I thought a little (very little) humor was called for. I know ranking is serious business.
