When you create a thread, please ensure than the event date, situated above the box where you type the details of the event, is the date of the event. It defaults to the date you create the thread and it is probably going to be some time before the actual event.

This will automatically add the event to the calendar and when the event is 60 days or less away it will appear in the list at the bottom of the forum home page. This means more people will see your event and you will get more interest.

I've had to edit several events recently where people have incorrectly completed the details.
