What I would change:
First and foremost, I think our (inter)Nationals needs to put more focus on encouraging all PNMs to rush, not just music majors/minors. I run in to so many people who think you need to be a music major to be in DO, when that is very much not true. (I guess that's just a personal one, since I'm totally un-musical

)
Second: Our website. It's hideous. They redid it about this time last year, but it still looks like it's from 1993.
Third: Better alum structure. It's sad when an alum chapter can meet 4 times a year, not do anything for the collegiates, and still win "Alum chapter of the year" awards.
