Accurate Voting on PNMs

[satb]

Hey Ladies,
I was wondering if any of you/your chapters had a better way to keep track of PNMs for voting. At the end of each party we all rush to our tables to vote on the girls we talked to. With the help of a booklet of pictures, we try to remember all the girls and how we felt about them.

Basically, I was wondering if your chapters had any ways to, while the party is going on, make note of the girls you talked to and their rank without slowing down bumping and letting the PNMs know that you are doing so. One girl in my chapter used to keep a small piece of paper with names and her vote but that system won't work for an entire chapter.

Thank you in advance for your help!
