Once your initial event posting has been saved, you can now add some custom design to your event page.
Once logged in, you can click on the Manage Events button or under "My Account" (top right of your screen) you can also find "Manage Events".
Next, click on the event you want to update:
When your event is in view, click on the "Add Splash" menu (menu to the left side of your event as shown below):
Next, click on "Custom" (see radio button under Palette Options). You can fully customize all of the different elements on your event page (backgrounds, text, buttons, etc). The Preview section shows a relative representation of your changes. You can make as many changes as you like, or simply click on the "Standard" radio button to revert back to the generic view. Once completed, simply click on the "Apply Changes" button (bottom right of page) to complete. You can also come back and make as many changes as you wish at any time.
