All candidates for President must declare to the BOD their intent to run by 17-MAR, 35 days before the election.
This new rule was added a few years ago as a courtesy to declared candidates.
The 35-day rule does not apply to Directors on the Board. They can be nominated all the way up to the day of the election.
But, a committee has formed to receive nominations and run the election. You don't need to wait until the last minute to nominate.
