Taskbarn’s easy-to-use project management tools will make your life easier. Communication, sharing, and planning are important elements of every project and Taskbarn helps you with all three. With Taskbarn, you can: a) Organize all project tasks in a TODO list; b) Communicate with project members through private messages and the project feed; c) Share files, web links, and other assets; d) Invite clients, colleagues, and friends to collaborate with you on your project; and e) Access your projects from anywhere with an internet connection. Your projects are private and secure. Only those who you invite can see your project, communicate with you, and share with you. All of your files, private messages, and project feeds are accessible only to invited friends. This has been added to the tools section of Research Rdesources Subject Tracer™ Information Blog.
