Many people are daunted by the titles, but while critically important jobs, they aren't that demanding.
The President's primary function - and it can be his or her only function if that's all they want to do - is to call and chair meetings. Vice-President is back-up for when the President can't take a meeting. Everything else can be done by the various committee chairs, and joint action is by consensus at the executive meetings. And there aren't usually a lot of those - between meeting communication is pretty easy, these electronic days, and generally the different committees just get on with their own jobs. The President can, as a member of the board, be involved in more if he or she chooses, but it's not a requirement of the office.
The Secretary, likewise, has one job - keep minutes of the meetings - and there's usually a lot of help with that. A detailed agenda (assembled from input by the board) is the outline right there, and you have everyone's help with any bit you might have missed. And very occasionally, there might have to be a letter written. The board, as a whole, helps with composing it, and the Communications Committee can help with the distribution.
The Treasurer's job does require some experience in accounting and reporting, but we don't have a huge budget, so it's manageable.
The big thing is, President and Secretary are both slots that need filling right now, so please consider putting your name forward for one of them...
