You can add events to this calendar of hang gliding events. Google Calendar (this application) requires that I add your email address to the list of folks who can edit this events calendar in order for you to be able to add events to the calendar.
So just send me your email address and I will add it to the list and I will reply with a notification when you are cleared to edit.
Once cleared to edit, open this calendar again (//ozreport.com/eventcalendar.php), and click the "Google Calendar" button on the lower right corner of the calendar and make your edits. You'll be prompted to sign in to your Google Calendar account or to create a new one on the spot, after you click this button.
