I've not been directly involved in expansion, but I think one thing you can bring to the expansion committee is your views as a collegian. If you were on a campus, what would you like to see in an expansion presentation? What would make you come to an open meeting? What works and what doesn't, so to speak. Even though I've been out of school a relatively short period of time (6 years, but for 3 of those I was back working on my masters), the culture on college campuses has changed, and sometimes what I think is a good idea really isn't. So give those expansion leaders some insight into what the current culture is. I'm sure you can also help in actual expansion presentations on other campuses.
By the way, congratulations on being selected!!
