Hey, I've given this away to so many people recently, so I thought I'd make it free for all to use. You don't have to edit any of the GUI stuff, all you have to do is edit the script in ReplicatedStorage. There's comments by everything to help you, but feel free to pop me a message if you need to. All you need to use this is a Trello board, it can be public or private. Just make sure you have a List of cards called "Applications", that's all there is to it!
