Add-to-Calendar is a special feature available for additional charge through AvantGo professional services involving the creation of a PIM "pod" that allows your PalmOS viewers to instantly add event reminders to their Calendars. Since this feature is only available for Palm devices, you should create two versions of your campaign to avoid confusing PocketPC users. If your ad is to have Add-to-Calendar functionality, you must include a form button in your jump page that the user will tap to add the information to their Calendar. All you have to do is put the button where you want it to appear on your page and label it exactly as you want it to appear.
