My department is trying to keep track of multiple projects and deadlines. We are running Microsoft Office 10 (which is Citrix based) and my boss also uses an Android tablet. I don't want to set up project deadlines as appointments in Outlook considering many project tasks span several days or weeks. Google separates out calendars and tasks. Are there any third-party internet websites, preferably free, that have calendar based task lists with categories. Ideally it would be one account that everyone could put all of their projects and deadlines on. I am not interested in Microsoft Project as it is too cumbersome nor do I need Gantt charts either.

Thanks-
