If I need to organise a meeting, I can currently look up the availability of people (who granted me access to see their availability).
However, I can only check this for ONE given event date & time. It would make planning much easier, if you could see, who is available when e.g. in the next week.
So could we have a calendar view (day / week / month), which simply shows the availability of people I select from a list?
Then GroupOffice really could compete with Doodle!
