When I first browse to trello.com there is no request for login or password or any screening of any kind. The result is that anyone sitting at my PC can click on the Trello icon/shortcut and be presented with the full list of all boards I have created, ie., Trello assumes that the PC operator is always me.
How do I stop access to the main Trello screen listing the boards I have created?
Example: if someone operates my PC and browses to yahoo.com or even my.yahoo.com they are not presented with all my activity. In fact they would not even know if I had a Yahoo account.
How do I force a logon to my "home" page on Trello?
