Honorary Greeks

I've noticed that alot of celebs are honorary greeks. What does this mean and are they officially members cause some of them didn't even go to college.

Honorary member, are for all intents and purposes, are members of their respective organizations. The difference is the rights they have with chapter/national activities. For example: I'm pretty sure that honorary member sdon't have the right to vote on new leaders like active members do, or plan functions for chapters to partcipate in. They are still members, but only to a certain extent.
