Can the IRS tell you who can be on a 5031c board?

Please explain, the IRS does not give you a list of names of people who has to be on the board. They may have restrictions as to people who have other ties to vendors and the such.

What I am asking can they tell if a husband and wife can be on the same board?

You can put anyone on your board. If I remember the IRS booklet on 501c3 correctly, you don't even need a board. You only need a president, treasurer, and one other, I forget, VP? There are not for profits who put the people they are serving, such as felons or the mentally ill or drug addicts on their boards.
