GoPlan – Online Project Management and Collaboration Tool
http://www.goplan.info/

Manage multiple projects with ease using Goplan’s intuitive user interface. No click-trickery to get to the information you need to work on – all your projects are immediately accessible from your account dashboard, next to your assigned tasks, issues and calendar events. Track project progress through task management, calendaring, note sharing and issue tracking. Additionally, real-time in-browser chat lets you converse with team members. Get notified of what happens on your projects with email and instant messaging (coming soon!) notifications. Use RSS feeds and sync the Goplan calendar to your iCal, Outlook or phone to stay on top of dates and tasks. When tighter integration is necessary, the Goplan developer API allows you to integrate our system to the rest of your infrastructure. Other people are using the Goplan API to build productivity tools on top of the Goplan platform. This has been added to the tools section of Research Resources Subject Tracer™ Information Blog.
