Can the Directors delegate there contact information only through the Management company?

Although your question does not expressly discuss this as the topic of your question, I presume that you are asking about the Board of Directors of a Common Interest Community or HOA.  Pursuant to NRS 78.150(3), each private corporation in Nevada must file its Annual List and disclose "(d) [t]he address, either residence or business, of each officer and director listed, following the name of the officer or director. . . "  HOAs are generally nonprofit corporations.  Pursuant to NRS 82.193, nonprofit corporations have the same filing requirements. The key phrase for the filings is that the address listed is "either residence or business".  Where this issue arises frequently in HOAs is that members of the Board of Directors do not want their home addresses and telephone numbers published for fear of having irate neighbors bothering them at home and thus they list their business address for purposes of the HOA as care of the management company.
