If you have two accounts at a certain website and you are tired of having to log in and log out all the time, try using multiple browsers. With the popularity of alternate browsers to IE, such as Firefox and Opera, you can save your settings for one account in your first browser and then the settings for your alternate account in your second browser. Since the cookies each browser sets are stored in different locations, they will not conflict with each other.

This particularly comes in handy if you have multiple email accounts at the same provider or you want to view data from one of your accounts while logged into another.
