If you are a freelancer and/or part of a virtual team, Producteev.com may be helpful for you and your team to stay on track! I was introduced to Producteev, a free online project management platform, when I commissioned a major website and rebrand for the Golandsky Institute. We had hired a web developer in Tennessee, but we are based in New York/Philadelphia.
Instead of countless emails getting opened/misplaced/lost, Producteev allows all team members to input info, attach documents and photos, assign tasks to specific people, and check items off the list. A very helpful feature on the platform is the ability to schedule deadlines for each specific sub-project or task.
There is also a mobile app with a simple interface that is extremely valuable when traveling, but allowing you to easily stay on top of multiple projects and teams simultaneously.
