THE LIST:
5 adzuki bean
5 anasazi bean
5 black beans
5 black-eyed pea (cowpea)
5 black lentil/urad dal
5 brown/Spanish lentil
5 cannellini
5 chickpeas (chana dal, garbanzo, ceci)
5 fava bean/broadbean
5 green/french/puy lentil
5 kidney bean
5 lima bean/butter bean
5 moth bean
5 mung
5 navy bean/great northern
5 red bean/chili bean
5 red lentils (masoor dal)
5 runner bean
5 pigeon peas (toor dal, gandules)
5 pinto
5 split peas
5 soybean

The rules:
1. You may vote once per day
2. Vote by adding a point to a bean you like, and subtracting a point from a bean you don't
3. When a bean reaches 0 points, it is eliminated and cannot be voted for again.
4. If the game eventually becomes stagnant and there's no clear end, there will be a poll of some nature to find the winner. We'll agree on a method for the poll. Some options:
vegweb poll to vote for one option
a write-in poll to vote for one or several options (each person lists there top 1 or top 3 or whatever in their post)
a write-in elimination game where things are nominated for elimination on a daily basis. i.e., people just write-in what they want to be eliminated that day, and the item with the most votes after 24h is eliminated. In this option there is no voting for things, only against.
