Yes Todd, exactly! i tested the system about a half year ago and I was already then pretty impressed about the powerful things that opengoo can manage.
Now I looked again for a project management tool inclusive a calendar, tasks, email, and contact management. OpenGoo give me everything I need. I'm looking forward to see this project growing. Maybe with stuff like syncing the calendar with my other/private google calendar or the same with the documents which I manage with google docs.
I also tested some other tools, but OpenGoo really gives me what I need for my Projects.
However, great work, let's go!
