Sometimes things just don’t need a comment but I agree with OTW. Bringing an NPC to campus does not happen overnight, not that any other inter/national group does either.
I just figured that
if the OP would be interested in an NPC member group, she would go to the NPC web site, link provided by TPAGirlie, and get the extension materials. It details the process step-by-step. The NPC Extension Chair can help to facilitate the process by speaking with university officials and so forth at the appropriate time. However, those types of mechanics can get confusing on a message board so sometimes it’s best to just go to the NPC web site first. Download and read the materials and then ask questions but that doesn’t always happen.
