Other gender Advisors/Honorary?

[naraht]

For those fraternities/sororities which only allow undergraduate members to be of one gender (which is most of those discussed here on greekchat), does your organization allow either Advisors or Honorary membership of the other gender. More particularly, is there any situation in which someone of age 50 (for example) of the other gender would be able to either go through the initiation ceremony or attend it.

Note, my reason for asking is trying to get context for the efforts of some Alpha Phi Omega (which did not allow women full membership until 1976) chapters to grant Honorary membership to women staff members in the 1960s and one chapter being allowed to have a female advisor in 1969.
