emailing agenda to specific member

I can email the agenda to all, President, VP ED,but not to the secretary or a specific member. How can I get the Secretary on that list?

Thank you,
Larry Cosgrove, Secretary
Speakers by the Sea 596351

That is a system list and is not likely to be changed unless there is a strong justification for adding the secretary as a specific addressee.  You can send it to "All Officers".  For your club I notice that the Secretary is also the Website Administrator, who happens to be on the list.
Alternatively, you can print the agenda to PDF format, and email that to a specific member.
