You have created a location. Then you added a lot of games to that location, only to notice later that the address was supposed to be 1414 instead of 1313. What to do? Well, change the location to the right address of course.

To start, you need to click on the Locations link to take you there, and then click on the name of the location to change. On the View page for the location, click on the Edit Location button on the Admin Links bar. Now you can make your changes. Once your finished, click on Save Location, and it will be updated for all the games linked to it.
