Setting up a grid in isocket is pretty easy. Click on the "Inventory" tab and then the green "Create New Ad Zone" button to start the process. When selecting the type of ad, you will have several grid options to choose from, including 2x2, 1x2 and more.
When you get the ad code for a grid, be sure to copy and paste the code in the correct number of times and format the code correctly so that it displays on the screen the way you want.
