There are 2 kinds of polls in vBulletin.
Multiple choice, which allows the user to vote on 1-N items, and each vote has the same weight.
One choice, which allows the user to pick 1 favorite. Each vote has the same weight.
These kinds of polls appeal to me (maybe one of them is close to what you are talking about?):
Preference (point system) - give 1~5 scores on each item on the list. Each person's vote counts as 100%, but they can give different weights to each item. If they only vote on 5 out of the 15 items, then their "points" are distributed that way.
We did this for the fish ranking.
Ranking, Each user can pick their top 3 choices, and they are weighted 60%, 40%, 20%.
If we did the 'arranging' as you mention (the javascript involved would be a nightmare, how about 10 drop-down menus for first choice, second choice, third choice, etc. and as you select items, it removes them from the other menus?)
what if they only vote on 5 out of the 15? What if someone else votes on 12 of them?
I would hope that each person's vote counts as "100%" somehow.
This would be a GREAT PHP project for you (although you could write it in less than 10 lines of
www.Rebol.com, this is what Rebol does best).
#1 I can't wait for the Rebol documentation to improve.
#2 How do you deploy Rebol on a website?
