Quorums
Following are guidelines per Robert’s Rules of Order Revised:

"In any deliberate group or board with an enrolled or specified membership whose by-laws do not specify a quorum, the quorum is a majority of all the members, by common parliamentary law."

"If a quorum fails to appear at a regular or properly called meeting, the inability to transact business does not detract from the fact that the rules requiring the meeting to be held were complied with and the meeting was convened and adjourned."

"The only action that can legally be taken in absence of a quorum is to fix the time which to adjourn, recess, or take measures to obtain a quorum."

This simply means we must have four (4) of our seven (7) Extension board members present to constitute a legal quorum unless specified otherwise in their own by-laws.

Proxy Voting
"Proxy voting is not permitted in ordinary deliberate assemblies unless the chapter or by-laws of the organization provide for it. Ordinarily it should neither be allowed nor required because proxy voting is incompatible with the essential characteristics of a deliberative assembly in which membership is individual, personal, and non-transferrable."
