Basecamp is a project collaboration tool. You can try it for free with some limitations, or you can pay for their service which allows you to take advantage of more features.
Some features include:
- Assign to-dos and tasks
- Post messages and gather feedback
- Share files internally or with clients
- Track peoples time
- Make milestones
Iâ€™ve used Basecamp on several projects and Iâ€™ll have to say that it is a great tool for keeping team members up-to-date.
