I started using Trello about a year ago and it is an amazing collaborative and organizational tool. To be honest the linkage to my work Google account and docs makes it super useful. If you are like most people your Google Drive has become a huge resource, but it is completely unorganized. Enter Trello. Get groups together, share resources, and make things happen. You can also add stickers, create collections, archive, print, export to pdf, just to name a few. This is the organizational tool of the future. Try Trello!
