Hmmm. You are not a member of the committee; you are the board liaison to the committee.

Back around 2005, the board decided to eliminate committee liaisons since committees felt the liaison tended to have too much influence on the committees. A few years later liaisons were re-established with the proviso that liaisons were there to observe and report back to the board, not to be a driving force in the committee activities.

I can recall liaisons even refusing to participate in committee discussions. I also recall one committee chair (Budget & Finance as I recall) telling the liaison to stop talking and only speak if asked by the chair to do so. 

I have a sense liaisons have become overly involved in committee operations again in recent years.
