Quorum: is defined as the smallest number which is greater than 50% of the number of current members.
Current members: individuals who have voted in both of the two previous meetings.

In other words: Quorum "floats" to match half of whatever the current level of participation is. If someone misses a meeting (or is new) they won't count towards quorum for the next two. It does not mean that they cannot vote.

The list of current members at the top of the page is for reference, anyone may note that so and so voted in some Editorial Board meetings and adds that name. Edit history of a page is the real proof of participation. there must be an edit in that month by that person.

If consensus is not reached on a particular motion, a vote will decide on accepting or rejecting a motion. It takes 50%+1 "current" members voting (for, against or abstain) to decide a motion. For example if the number of current members is 7, then quorum would be 4, which means that if two vote in favor, one against and one abstains, the motion passes.
