So far, i think its wise enough for a traffic to use it and easy for a boss to scan through it.

The google calendar idea, i tried previously, together with using Google Sites as a project site and having pages / gadgets, somehow, it aint so productive and intuitive although control is there…

Perhaps working that way with internal team mates may work…while ActiveCollab will work with both internal and external team.

As a client/PM, it’s useful to track milestones and deadlines.

As traffic, you’ll end up spending too much time trying to keep track of the changes on all your calendars.

As a boss, you prolly subscribe to none and make your PMs tell you about their calendars once a week.

I think useful for everybody but the Traffic person.
