I would like to create a forum online that allows upvotes and downvotes and organizes posts according to upvotes and downvotes. I remember a site a while ago that had the EXACT design I'm looking for: http://oneupme.com/. This site lets users answer a question and then vote on the answers. It organizes the answers according to number of votes. That's all I want, preferably with as minimalist design as possible. I want to use it to make study tools: for example, to remember the fact: "Kingdom, phylum, etc..." there are certain acronyms such as "King Phillips etc..." I want to display a fact and then let users invent the acronyms and then vote on those inventions. Whoever is best will be at top.
