I have a number of boards and want to see all my outstanding tasks. Is there one place where I am able to do this, without having to go to each board individually?
The answers in this thread might be helpful: Is it possible to view cards across projects by due date on Trello?
The first answer points to a third party site Trello Calendar and the second mentions a card on the Trello development board discussing a similar feature.
Hope this helps.
Since the Trello calendar from Jacob's answer doesnt work anymore but still some users come from google,
try this http://trello-calendar.w11k.de - its a calendar with all of your cards of all boards.
