The ability to have multiple people collaborate on different parts of one project is great, for example I can work in my office while someone else works from home, we both share our progress without having to constantly email each other or check-in with others. Also it's easy to use as you don't even really need any training to get started using it! There are some features that aren't intuitive at first (like how to find your previous comments). It would be nice if there was the option to create custom colors instead of limited options like black/white but overall this program has been very useful so far. We're solving problems by allowing all team members to easily communicate ideas and tasks between them and also keep track of their own time spent on projects.
