Here's a post guaranteed to get two thumbs up from Drew McManus: if you're a nonprofit organization - and how many US orchestras and opera company aren't? - your web site should include an easy-to-find list of all officers and trustees of your organization.
That's not particularly difficult to do, either, so I am rolling my eyes over the fact that I'm having to contact press offices to get my hands on a list of the trustees. Officers, easy to find; trustees, buried or not listed. Transparency, people, transparency!
