I think it is better for the sorority names to be anonymous. The PNM feels less pressure and no one feels offended that you didn't like their house. I love ADPi, and I know I would feel sad if someone outright hated the chapter at their school when they were going through. I might even feel a little awkward about posting to that person after they became a sorority sister, just b/c of what they said about my sorority. Make sense?
To make it fun, I would like to propose this to our Rush Moderator:
Let's have a role call of all PNM's. They can all pick a theme for themselves (candy, colors, flowers, etc.) And then, they can personally assign each house something to do with their theme-- ie: if they are Candy, there is the Mallomar House, Hershey House, Sweettarts House, etc....
