We have been using Trello to manage and track various tasks for our WordCamp in Mumbai, so we create a Card (Allows us to vote/comment/add attachments) for each application on a list for speaker applications as they come in and track them, if rejected the card gets archived, if approved they move to lists where we plan the schedule.

But this seems like a good Idea to try as well.

Is this a plugin made available on the WordCamp Websites, if not you should recommend that it's added...
