On-Line Collaboration

Have you been looking for a way to collaborate with many people in your group, organization or family?  I stumbled on a very simple to use on-line service that allows you to do just that.  It is intuitive and versatile.  It provides a shared workspace for files and discussions, tasks, calendar, database, reports or a blog.  More utility than Google Docs and Google Groups combined.  Check it out and sign up for a free trial.    http://signup.centraldesktop.com/tresource
