Oooh, I just LOVE honor societies.
As everyone said, you can indeed hold membership in a social GLO as well as academic and professional societies. Just keep organized, and don't bite off more than you can chew.(Being an officer in three organizations is harder than it sounds.) But most importantly, keep up the great work! And let your social GLO know what a smarty you are!
