Thanks a lot for reaching out about the plugin. When you talk about board and committee members who are editors, are you referring to their role in WordPress?
Right now there are only two roles in WordPress that can use the board management system. Board members, who don't have permissions to work with the website's content at all outside the board management tool, and administrators, who obviously have access to everything within the WordPress system.
If the board members are "editors" in WordPress, they won't be able to use the board management tools unless they're promoted to administrators or they create another account using a different email address.
I hope that's helpful. Let me know if I can answer any other questions.
