Trello is a highly customizable digital bulletin board that you can use to set up anything from to do lists, tasks, notes and more. Users create "lists", which are dynamic containers that can be filled with "cards." These can be anything from tasks, notes, ideas, pictures and more, that users can then drag and drop up and down the line, or move to other lists. All of this can be shared with other users, with provisions for creating new cards, adding comments, and assigning tasks. Trello's neutral design makes it flexible enough to be used for a variety of organizational tasks, whether you're coordinating a team, keeping track of your personal projects or just creating your own idea board.
