Is there a tool that would allow a group to create a list with upvote functionality?

Per @assafhaski's suggestion. Just enable the voting power up and you're good to go.

Could set this up super easily and just lock the site behind a login using a plugin. I'm running it as an internal suggestion tool at my company with a Google Apps login required.

Telescope would be great for this use case - it allows you to build your own Hacker News, Reddit, or Product Hunt.

I would consider creating this custom using the following in the following ways: 1) Setup and get a Mlabs account working that will save submitted data on button-click to your MongoDB, I used https://glitch.com/~adam-mongo-test recently to setup my own private messaging domain, but you're going to want to configure https://glitch.com/~fcc-voting-a... which is closer to what you want (a real-time voting feature) 2) Most of the work is already done for you within the glitch project mentioned above, to make it more of an up/down vote experience simply change the UI: > When the upvote arrow is clicked execute what the 'vote' button would do per item, if the downvote is clicked however you will need to review some Mongoose to understand how your scripts can update your MongoDB and then send this new downvote data to the graph. 3) To get all the upvote UI just use jquery upvote at http://janosgyerik.github.io/jqu... Great thing about this option is that anyone can add a new Book title and it can start receiving votes instantly after being added. Once you get it working you can simply embed the upvoting system using an iframe: From what I can understand, if you have code experience this solution is going to give you exactly what you want, If you want me to build this for you, I'd charge $1000, and show you exactly how it works and how to use and maintain it.

has a very great portal for ideas but complicated to set up. easy for users and general public to suggest ideas and front end design is quite ok. was a better solution than trello. its also expensive but they have startup pricing.

Hi @ndewilde, Trello seems to be perfect for this! Alternatively, we're working a Slack integration (https://slido.slack.com/apps/A4B...) that allows you to crowdsource ideas (or books) in a Slack channel where anyone can upvote their favorites and you can either present the top ones or export the list. Would love to hear your feedback on this!
